By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary. Here is a sample; alter the names: + + Yoyodyne, Inc., hereby disclaims all copyright interest in the program + `Gnomovision' (which makes passes at compilers) written by James Hacker. + + , 1 April 1989 + Ty Coon, President of Vice + +This General Public License does not permit incorporating your program into +proprietary programs. If your program is a subroutine library, you may +consider it more useful to permit linking proprietary applications with the +library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License. diff --git a/ChangeLog b/ChangeLog new file mode 100644 index 0000000..6111246 --- /dev/null +++ b/ChangeLog @@ -0,0 +1,75 @@ +vchanger ChangeLog + +1.0.1 (2015-06-09) + - When looking up the mountpoint of a magazine by UUID with libudev, + also look for mountpoint of device alias names in DEVLINKS in addition + to the DEVNAME.

Usually, + the default options will suffice to install vchanger under the + /usr/local directory. + + Some systems require unusual options for compilation or linking that + the `configure' script does not know about. You can give `configure' + initial values for variables by setting them in the environment. Using + a Bourne-compatible shell, you can do that on the command line like + this: + CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure + Or on systems that have the `env' program, you can do it like this: + env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure + Or if you're using a non Bourne-compatible shell, you can do: + sh -c 'CFLAGS="-O2 -g" ./configure + + A typical vchanger development configuration for Linux is: + + CFLAGS="-g -O2 -Wall" \ + ./configure + + 2. Carefully review the output from ./configure. If it is not + what you want, re-run the ./configure. Often ./configure "caches" + things and thus remembers the last ./configure options. If you + want to be sure you are starting fresh after a ./configure, + do a: + + make distclean + + before re-running ./configure. "make distclean" wipes out any + knowledge of the ./configure, so don't do it after you have a + configuration that suits your needs, otherwise the "make" will + not work. + + 3. Build it + make + + 4. Install it + make install-strip + + 5. Create a autochanger configuration file and configure Bacula(TM) + to use that autochanger. Please see the documentation in the + ./doc directory for details. diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..8949d4d --- /dev/null +++ b/Makefile.am @@ -0,0 +1,13 @@ +AUTOMAKE_OPTIONS = foreign +SUBDIRS = src doc scripts +docdir = $(datadir)/doc/$(PACKAGE)-${VERSION} +doc_DATA = AUTHORS \ + ChangeLog \ + COPYING \ + INSTALL \ + NEWS \ + README \ + ReleaseNotes \ + doc/vchangerHowto.html \ + doc/vchanger-example.conf \ + doc/example-vchanger-udev.rules diff --git a/Makefile.in b/Makefile.in new file mode 100644 index 0000000..8351f19 --- /dev/null +++ b/Makefile.in @@ -0,0 +1,817 @@ +# Makefile.in generated by automake 1.13.4 from Makefile.am. +# @configure_input@ + +# Copyright (C) 1994-2013 Free Software Foundation, Inc. + +# This Makefile.in is free software;

These changes allow for an unlimited and variable + number of volume files on each magazine, and allow adding and deleting + volumes to/from magazines, as well as moving volume files from one + magazine to another. Virtual drives are now symlinks dynamically + created by the LOAD command. An unlimited number of virtual drives per + autochanger is supported without requiring a vchanger configuration + change. The number of virtual drives used is determined solely by the + Device resources defined in bacula-sd.conf. + + Also, vchanger will now automatically issue 'update slots' and + 'label barcodes' commands to Bacula via bconsole when it detects a + change in the availability of any of its defined magazines or when + volume files are created with the CREATEVOLS command. Together with + an automounting mechanism, this makes the attachment and detachment + of removable drives a plug-n-play operation. + + To aid in using removable drives on systems having udev, vchanger now + includes a udev rules generator and helper scripts to enable the + automatic mounting of magazine filesystems triggered by udev hotplug + events. The advantage to using this automounting method, as opposed to + autofs or window manager automounters using dbus, etc., is that these + scripts will invoke vchanger with a new REFRESH command that will issue + an 'update slots' command via bconsole whenever removable drives + are attached or detached. + + Change Summary: + + The concept of a 'magazine' has changed. A magazine remains a + directory, usually the mountpoint of a filesystem, however no metadata + files are now stored on the magazines and volume files are not renamed + when loading and unloading virtual drives. There is now no requirement + that all magazines have the same number of volumes, and volume files + may have any filename. New volume files can be created on a magazine + at any time. A new extended interface command, CREATEVOLS, has been + implemented for this purpose. A magazine is now simply a filesystem + (or directory) containing some variable number of volume files. Any + directory containing volume files can be used as a magazine in + vchanger, including for example volumes created using Bacula's + built-in disk storage handling. Volume files may be deleted from + magazines or moved between magazines. The only caveat is that the + volume's Media Type must match that of the autochanger's Storage + resource. + + Virtual drives are now simply a symlink in the autochanger's work + directory. The drive number is the name of the symlink. For example, + if the autochanger's work directory is /var/spool/vchanger/changer1, + then virtual drive 0 is a symlink at the path + /var/spool/vchanger/changer1/0. The symlink's path is then specified as + the Archive Device in the Device resource defined in bacula-sd.conf for + the autochanger's drive 0. Vchanger implements the LOAD command by + creating this symlink pointing at the volume file mapped to the slot + requested to be loaded. A subsequent UNLOAD command deletes the + symlink. In previous versions, a LOAD created a symlink pointing to the + mountpoint of the magazine and then renamed the volume file on the + magazine to 'drive0', 'drive1', etc. This was because the original + design criteria, (dating to before the release of Bacula 2.0.0), + required that vchanger run on Windows Server 2003, which did not have + the capability of file-level symlinks. However, file-level symlinks is + a much more robust method, handling any "out of space" conditions in a + clean, expected way. For that reason, use of vchanger on versions of + Windows without file-level symlinks is no longer supported. + + An autochanger's magazines are assigned in its vchanger configuration + file. An unlimited number of magazines is supported and the storage space used + by an autochanger can be scaled at any time by simply adding additional + magazines and creating volume files on them. Expansion of the storage + space does not require any change to Bacula's configuration. Any + combination of one or more of the assigned magazines can be attached + (mounted) at any time. + + When a magazine is attached or detached there is of course a change in + which volumes are available for reading and writing. Bacula must be + instructed to update its database to reflect the change. This is + analogous to swapping tapes in a tape autochanger library. Bacula has a + bconsole command used for this purpose, the 'update slots' command. In + general, one would insert or remove tapes and then issue an 'update slots' + command in bconsole to inform Bacula of the change. With vchanger, + attaching or detaching a magazine also requires that the 'update slots' + command be issued, however vchanger now detects changes to the currently + available volume files and automatically issues the 'update slots' + command when needed. This allows swapping magazines to be a true + plug-n-play operation. + + The scripts directory in the vchanger source tree contains a script to + generate the udev rules needed to automatically mount the magazines + filesystems defined in the vchanger configuration file. These rules will + cause udev to launch scripts, also included in the scripts directory, to + handle a "hot add" event by mounting the magazine filesystem and invoking + vchanger with the REFRESH command to issue an 'update slots' command to + Bacula. Likewise, a "hot delete" event will launch a script to unmount + the filesystem and again invoke vchanger with the REFRESH command. + + If vchanger is compiled on a system supporting udev, then libudev will be + used to determine the device node of magazine partitions specified by + UUID. If compiled on a system without udev, the older method of using + libblkid and libuuid will be used if available. For Windows builds, + win32 API functions are used to map filesystem UUID to device node. If + the getmntent() function is not available on the target system for + determining a filesystem's mountpoint, then vchanger will use the + getfsstat() function, allowing magazines to be specified by UUID on many + BSD and OSX systems. A build for a minimal system having neither libudev + nor libblkid will succeed, however specifying magazines by UUID will not + function and result in an error, meaning that such minimal systems must + only specify magazines by directory path. These changes should alleviate + many of the problems people have had in the past building vchanger for + non-Linux systems. + + Bugs Fixed: + 5 Compile errors on Debian or Ubuntu + 6 Broken libblkid returns wrong device for UUID + 7 Limitation on number of virtual drives + 8 Compile errors under Solaris 10 + + ================================================================== + + + Release 0.8.6 + + When using the automount_dir directive, opendir() is now used rather + than stat(), to trigger automounts. For some combinations of Linux + kernel and older versions of autofs, stat() is not sufficient to + trigger an automount. + + Extensive logging was added to this version, along with a new + configuration directive to set the logging level. This should greatly + help problem diagnosis. + + State information for the magazine bays is now kept in the work + directory along with virtual drive state. In a multi-magazine changer, + when a magazine was unloaded from a bay, magazines in higher numbered + bays were being shifted down to appear loaded into a different bay + than they were before the magazine was unloaded. With this version, + magazines will remain loaded in the same bay until they are unloaded. + + Bugs Fixed: + + ================================================================== + + + Release 0.8.5 + + Minor bug fix release. Fixes link errors for older versions of + e2fsprogs on some distros (bug 4). Also applies the "safe strncat" + patch to prevent a buffer overrun present in strncat in some standard + C libraries. + + Bugs Fixed: + 4 Compile errors related to e2fsprogs libraries + + ================================================================== + + + Release 0.8.4 + + This release is a bug fix release. All users of version 0.8.3 should + upgrade to 0.8.4 to prevent a bug causing Bacula to mark volumes in + error. + + Change Summary: + The slot number passed in parameter 3 is now ignored for the LOADED + command. This should fix a bug causing Bacula to mark a volume + loaded into a drive in error when a job starts after the magazine + has been removed. + + Bugs Fixed: + 3 LOADED command fails when param 3 (slot) is zero + 2 Compile fail on FreeBSD 7.2 + + ================================================================== + + Release 0.8.3 + + This release adds the ability to specify magazine partitions by UUID, + making it much easier to use multiple simultaneous magazines. + + Change Summary: + + Specifying magazine partitions by UUID is a paradigm shift in the way + magazines may be assigned to a particular autochanger. Previously, + magazines were assigned to an autochanger by giving the magazine a + filesystem label matching the autochanger's name. Standard udev + rules on many distributions create a device symlink in + /dev/disk/by-label that allow easily configuring autofs to mount the + magazine at a known mountpoint. This works well for a single magazine + autochanger, but for a multi-magazine autochanger special udev rules + are needed to create unique device symlinks when all of the + magazines have the same filesystem label. Since the standard udev + rules on most systems create device symlinks by filesystem UUID + under /dev/disk/by-uuid, assigning magazines to an autochanger by UUID + makes it much easier to configure automounting that will work for an + autochanger with any number of simultaneously mounted magazines. + + Note that magazines may still be specified as a directory path, so the + previous methods still work, however it is recommended to assign + magazines by UUID if possible. + + As an aid to working with multi-magazine autochangers, a new extended + API command, LISTMAGS, was added to list the magazines currently + "inserted" into each of the autochanger's magazine bays. Like the + INITMAG command, it is an extension to the Bacula Autochanger API and so + is never invoked by Bacula. + + Bugs Fixed: + 1 Unable to detect when drives inserted using the vchanger + 2 Compile fail on FreeBSD 7.2 + + ================================================================== + + Release 0.8.2 + + This release fixes some documentation errors.

1. Introduction

+

This document describes how to utilize disk storage, particularly + removable disk storage devices, as backup media for a virtual autochanger + to implement a backup solution using Bacula, + an open source network backup solution. Bacula can use many types of + backup devices, one of them being robotic tape libraries, also known as + autochangers. Bacula utilizes these devices through an interface known as + the Bacula +Autochanger + Interface. Because autochangers are controlled in various + proprietary ways, the Bacula Autochanger Interface provides a generalized + method of interfacing with these devices by issuing commands, (such as + LOAD a tape, UNLOAD a tape, etc.), to an external script or program that + in turn implements the device-specific method of carrying out the desired + action. Vchanger is such a program, implementing the Bacula Autochanger + Interface to act as a virtual autochanger, using files on disk storage in + place of tapes.

2. Definitions

+

Bacula is an open source network backup solution. Much more + information about Bacula is available at the Bacula website http://www.bacula.org.

+

An autochanger is a backup storage device consisting of one or + more tape drives, a mechanical tape library where a number of tape + cartridges are stored, and an individually addressable robotic device + capable of physically moving tape cartridges between the tape library and + the tape drives. The tape library contains mechanical slots, each of which + can hold one tape cartridge. In most cases, the slots are located in one + or more mechanical magazines, (tape caddies), that can be inserted into + and removed from one or more or the tape library's magazine bays.

+

A virtual autochanger emulates a tape autochanger using disk + storage, rather than tapes. Note that in the strictest sense, vchanger is + not a tape library emulator, in that it does not implement a device driver + with SCSI command interface. Rather it utilizes an API implemented by + Bacula to manipulate autochangers.

+

A slot is a physical location in a tape library that may + contain one volume (ie. tape cartridge).

+

A magazine is a mechanical tape storage device having a number of + slots into which tape cartridges may be inserted. The tape library of many + autochangers consists of one or more removable magazines, allowing several + tapes at a time to be swapped into or out of the tape library.

+

A bay, or magazine bay, is a physical location in a + tape library into which a magazine (tape caddy) can be inserted.

+

A removable disk drive is a random access disk storage device + that is external to, or easily removable from, a computer system. Examples + are external drive enclosures that connect via USB, eSATA, and hot + swappable SCSI/SAS/SATA drive bays.

+

The term hot swappable refers to hardware devices that may be + attached to and removed from a running computer system.

+

A volume is a sequential stream of data written to a tape or + file that begins with a Bacula volume label that identifies the data + stream.

+

The term drive, unless otherwise stated, refers to one of an + autochanger's drives, a device capable of reading and writing data from/to + a single tape or volume file.

+

3. Overview

+

The Bacula Storage Daemon controls an autochanger by invoking a script or + program, passing it command line arguments defined by the Bacula +Autochanger + Interface. The interface defines a set of commands and associated + arguments to load and unload the autochanger's drives, determine which + volumes are available in the autochanger's slots, and to determine from + which slot a drive was loaded or if it is empty. The interface is an + abstraction, allowing Bacula to communicate with various different + autochanger hardware devices through the use of a common set of commands. + It is the script or program's responsibility to interpret these Bacula + Autochanger Interface commands and cause the underlying hardware to + perform the requested action. Vchanger is such a program, accepting Bacula + Autochanger Interface commands and treating a group of disk file systems + as a virtual autochanger. Rather than loading tapes from library slots + into tape drives, as the mtx-changer script does for tape autochanger + hardware, vchanger "loads" disk file volumes from virtual slots into + virtual drives by creating symlinks pointing to volume files located on + one or more filesystems or directories assigned to the virtual + autochanger.

+

Using autochanger interface commands, Bacula interacts with a vchanger + autochanger in exactly the same way as it interacts with a tape + autochanger. Therefore to understand how Bacula interacts with a vchanger + autochanger, it is necessary to first understand how Bacula interacts with + a tape autochanger. An autochanger is defined in the Bacula Storage Daemon + configuration file as an Autochanger + resource. The Autochanger + resource defines the Changer + Device to be the system file name (device node) of the tape + library's robot and the Changer + Command to be the command that Bacula will + invoke to perform Bacula Autochanger Interface commands. Normally this + command will be the mtx-changer script that is shipped with Bacula, of + course customized and/or configured to operate with the particular + autochanger hardware. Additionally, the Autochanger + resource defines a list of one or more Device + resources, (also defined in the Storage Daemon configuration), + that belong to the autochanger. Each of an autochanger's tape drives is + defined as a separate Device + resource. Each tape drive's Device + resource defines its Archive + Device to be the device node of one of the autochanger's tape + drives and its Drive + Index that defines which of the autochanger's tape drives that + particular device node pertains to. An example configuration for a two + drive autochanger is given below.

+ 
# /etc/bacula/bacula-sd.conf
Autochanger {
  Name = tapechgr
  Changer Device = /dev/sg3
  Changer Command = "/etc/bacula/mtx-changer %c %o %S %a %d"
  Device = tapechgr-0, tapechgr-1
}
Device {
  Name = tapechgr-0
  Drive Index = 0
  Autochanger = yes
  Archive Device = /dev/nst0
}
Device {
  Name = tapechgr-1
  Drive Index = 1
  Autochanger = yes
  Archive Device = /dev/nst1
}
+

When Bacula needs to load a tape from one of the library's slots into one + of its tape drives, it will invoke the Changer + Command, (the mtx-changer script), with positional parameters, + where parameter 1 is the Changer + Device, parameter 2 is the command to be performed ("LOAD" in + this case), parameter 3 is the library slot containing the tape to be + loaded, parameter 4 is the Archive + Device of the Device + resource (tape drive) to be loaded, and parameter 5 is the Drive + Index of the Device + resource to be loaded. Once the needed tape is loaded into a drive, Bacula + will open the device node specified by the Archive + Device (the device node of the tape drive) to read or write + volume data from or to the tape.

+

Since a vchanger autochanger is treated like a tape autochanger, the + configuration for a vchanger autochanger looks very much the same,

+ 
# /etc/bacula/bacula-sd.conf
Autochanger {
  Name = vchgr
  Changer Device = /etc/vchanger/vchgr.conf
  Changer Command = "/usr/bin/vchanger %c %o %S %a %d"
  Device = vchgr-0, vchgr-1
}
Device {
  Name = vchgr-0
  Drive Index = 0
  Autochanger = yes
  Archive Device = /var/spool/vchanger/vchgr/0
}
Device {
  Name = vchgr-1
  Drive Index = 1
  Autochanger = yes
  Archive Device = /var/spool/vchanger/vchgr/1
}
+
+

One obvious difference is that vchanger is invoked as the Changer + Command in place of the mtx-changer script, and with the Changer + Device passed as parameter 1 being the path to a vchanger + configuration file, rather than the device node of a tape library robot. + The only other difference is the Archive + Device setting in each of the Device + resources. Rather than the device node of a physical tape drive, + the Archive Device + of a vchanger autochanger's Device + resource specifies the path to a symlink that will act as a + virtual drive. When vchanger is invoked with the LOAD command, it creates + this symlink pointing to the volume file associated with the requested + slot number. This slot number is an index into a + virtual-slot-to-volume-file map maintained by vchanger. Just like the tape + autochanger, once the needed volume is "loaded", (ie. the symlink has been + created), Bacula will open the device specified by the Archive + Device to read or write volume data, in this case a regular file + instead of a tape drive device node. In the Unix way of treating + everything as a file, that is really only a minor difference. Details of + the vchanger autochanger implementation are given in section + 4 below.

+

3.1. What About Bacula's Native Virtual + Autochanger Support?

+

A Device resource's + Archive Device directive + determines the i/o device that will be used to read or write volume data. + Bacula handles the opening of the path specified as the Archive + Device differently depending upon whether or not that path + specifies a filesystem directory. If a Device + resource's Archive + Device specifies a directory, then when that Device + is opened Bacula will open one of the files in that directory for + reading or writing. Otherwise, if the Archive + Device is not a directory, then Bacula will directly open the + path specified by the Archive + Device for reading or writing.

+

For a Device + where the Archive + Device is not a directory, there can only possibly be one volume + available for reading or writing at any one time. For example, a tape + drive can only have one tape loaded at a time. For a + Device resource where the Archive + Device is a directory there, can be many volumes available. + Though a filesystem directory may contain multiple volume files, and + unlike a tape drive, could allow multiple volumes to be opened + simultaneously, Bacula purposefully limits a Device + resource to reading or writing only one volume at a time. This + abstraction is a good thing! It allows the remainder of Bacula's complex, + multi-threaded logic to treat all Device + resources in the same, consistent way. One Device + may read or write only one volume at a time.

+

Because this single volume restriction is not technically necessary for a + disk filesystem directory, one could define several Device + resources, all specifying the same directory path as their Archive Device. + Each of these Device + resources could have one volume file opened at a time. This will + allow multiple volume files in that directory to be opened simultaneously, + but will also force the operator to manually allocate backup jobs across + the available Devices. + The Autochanger resource + provides a means to group multiple Devices + together into a single addressable resource. Jobs can then be + configured to write to the single Autochanger + resource and Bacula will automatically handle the selection of an + available Device from + the group of Devices + assigned to that Autochanger.

+

An Autochanger resource + also defines a Changer + Command and Changer + Device. Ordinarily, for a tape autochanger, the Changer + Device defines the device node of a robotic tape library device + that moves tapes between library slots and one or more tape drives, and + the Changer Command + specifies a script or program that Bacula invokes to command the robot to + move tapes between library slots and tape drives. + When the Changer + Command  and Changer + Device are both null, Bacula has special handling that allows an + Autochanger + resource to be used with multiple disk storage Device + resources as a disk-based virtual autochanger.

+

For example, the following placed in the Bacula Storage Daemon + configuration defines a "native" disk virtual autochanger named FileChgr1 + with two virtual drives. The two Device + resources (virtual drives) allow two volume files to be open at + the same time, and of course more than two Device + resources could be configured to allow as many virtual drives as + needed.

+ 
Autochanger {
+    Name = FileChgr1
+    Device = FileChgr1-Dev1, FileChgr1-Dev2
+    Changer Command = /dev/null
+    Changer Device = /dev/null
+}
+
+Device {
+    Name = FileChgr1-Dev1
+    Media Type = File1
+    Archive Device = /backups
+    LabelMedia = yes          # lets Bacula label unlabeled media
+    Random Access = Yes
+    AutomaticMount = yes
+    RemovableMedia = yes
+    AlwaysOpen = no
+    Maximum Concurrent Jobs = 5
+}
+
+Device {
+    Name = FileChgr1-Dev2
+    Media Type = File1
+    Archive Device = /backups
+    LabelMedia = yes          # lets Bacula label unlabeled media
+    Random Access = Yes
+    AutomaticMount = yes
+    RemovableMedia = yes
+    AlwaysOpen = no
+    Maximum Concurrent Jobs = 5
+}
+

Notice that both Device + resources specify the same Archive + Device and Media + Type. This is because the Storage + resource in the Director configuration may only specify a single + Media Type. A + volume is given the Media + Type of the Device + it is written with. Since a location may have several tape drives + of the same type, Bacula uses the Media + Type to determine which volumes may be loaded into which Devices. + This, for example, allows Bacula to load a LTO-5 tape into any available + LTO-5 tape drive, while preventing Bacula from attempting to load the + LTO-5 tape into a LTO-2 drive. The same applies to the native virtual + autochanger. A volume file in one Device's + directory would not be found in another Device's + directory, and so with each Device + having a different Archive + Device directory, it would also be necessary for the Devices + to have different Media + Types to prevent Bacula from attempting to load a Device + with a volume file that does not exist on its Archive + Device. That in turn means that all of the autochanger's Devices + could not be associated to a single Storage + resource in the + Director configuration, and so defeats the purpose.

+

3.2. Why vchanger?

+

Because Bacula currently requires a Storage + resource to specify a single Media + Type, the native virtual autochanger is, for practical purposes, + limited to utilizing a single directory as volume file storage. If volume + files are contained in multiple filesystems, such as removable drives, + then those filesystems can only be mounted at that directory one at a + time. With vchanger, an unlimited number of filesystems may be + simultaneously mounted at different mount point directories with all + volume files on all filesystems having the same Media + Type. This allows an unlimited number of simultaneously available + volume files and an unlimited number of Device + resources (virtual drives), where any volume file on any + filesystem can be "loaded" into any of the autochanger's Device + resources using only a single Storage + resource in the Bacula Director. This gives vchanger the + following advantages:

+
    +
  • Available volume storage space can be easily scaled by adding + additional filesystems or directories
    • +
  • Scaling available volume storage space requires no change to the + Bacula configuration and no restart or reload of any Bacula daemons
    • +
  • All volumes have the same Media Type and so can be moved between + filesystems without any need to update volume information in the Bacula + catalog.
    • +
  • Filesystems can be specified by UUID and vchanger will query the OS + for the mount point when needed. This allows any type of automounting to + be used and the filesystems to be mounted at arbitrary paths.
    • +
  • It is very restore friendly. When volumes needed for a restore are + located on different filesystems, for example on multiple removable disk + drives, all filesystems containing the volumes needed for a restore can + be mounted simultaneously, eliminating the need for operator + interventions to swap removable drives.
    • +
+

By default, vchanger supports integration with Bacula through issuing + commands via bconsole. Whenever a change is detected in the volume file to + virtual slot mapping, for example when a removable drive is attached or + detached, vchanger will issue an update + slots command to synchronize Bacula's view of the autochanger's + available volumes. Also, when vchanger is used to add volume files to an + autochanger, a label barcodes + command is automatically issued to label the new volumes.

+

Vchanger also automates the generation of udev rules and scripts that may + be used to automatically mount and unmount the filesystems defined in + autochanger configuration files. When a removable drive is attached or + detached, a script may be launched by udev to mount or unmount the drive's + partition and issue an update slots + command via bconsole. These udev rules and scripts allow the attaching and + detaching of  removable drives used by vchanger to be a true + plug-n-play operation.
+

+

4. Virtual Autochanger Implementation

+

Vchanger implements the following Bacula + Autochanger Interface commands:

+ + + + + + + + + + + + + + + + + + + + + + + + +
+

LIST

+ 		+

Lists the slots and barcodes of currently inserted volumes

+
+

LOAD

+ 		+

Loads a volume from a slot into a drive

+
+

LOADED

+ 		+

Returns the one-based slot number where the volume currently + loaded into a drive came from, or zero if the drive is unloaded.

+
+

SLOTS

+ 		+

Returns the number of slots in the autochanger

+
+

UNLOAD

+ 		+

Unloads a volume from a drive and moves it back into a slot

+
+

Vchanger also implements the following + undocumented command defined in mtx-changer since Bacula version 5.1.0:

+ + + + + + + + +
+

LISTALL

+ 		+

Lists status information for all drives and slots

+
+

Vchanger also implements three vchanger-specific + extended commands that are not part of the documented Bacula Autochanger + Interface:

+ + + + + + + + + + + + + + + + +
+

LISTMAGS

+ 		+

List the status of configured magazines

+
+

CREATEVOLS

+ 		+

Creates empty volume files on a magazine.

+
+

REFRESH

+ 		+

Cause vchanger to refresh virtual drive and magazine state and + communicate any changes to Bacula.

+
+

The Bacula + Storage Daemon calls vchanger with 5 positional parameters defined as:

+ + + + + + + + + + + + + + + + + + + + + + + + +
+

Param 1

+ 		+

Path given by the + Changer + Device directive + in the Autochanger + resource. For + vchanger, this should define the path to the + autochanger's  vchanger + configuration file.

+
+

Param 2

+ 		+

Bacula Autochanger Interface command to execute

+
+

Param 3

+ 		+

The one-based slot number that the command is to act upon

+
+

Param 4

+ 		+

Path given by the Archive Device + directive of the Device + resource corresponding to the drive number given in parameter 5 + (ignored by vchanger)

+
+

Param 5

+ 		+

The zero-based drive number that the command is to act upon

+
+

Each vchanger autochanger requires a unique + configuration file and work directory. The configuration file specifies + the location of its work directory, defines the directories and/or + filesystems that are to be used for volume file storage, and specifies the + Storage resource + name, (as defined by the Name + directive of the Storage + resource in bacula-dir.conf), that this autochanger is associated + with. An autochanger's work directory is where vchanger will keep virtual + drive and magazine state information and where the symlinks to volume + files will be created for loaded virtual drives.

+

4.1. Virtual Magazines

+

Virtual autochangers using vchanger treat the directories and filesystems + assigned to them as "virtual magazines", each able to contain a variable + number of volume files. This is analogous to the mechanical tape + magazines, (tape caddies), that many tape autochangers use. These tape + autochangers have one or more bays into which removable tape magazines can + be inserted. Each tape magazine contains a fixed number of slots into + which individual tape cartridges may be inserted. The principle difference + is that tape magazines have a fixed number of physical slots, whereas + vchanger virtual magazines have a variable and unlimited number of virtual + slots.

+

Virtual magazines are filesystems or directories that are assigned to an + autochanger by including Magazine directive lines in the vchanger + configuration file. The order in which the Magazine + directive lines appear in the configuration file  determines + which "virtual bay" the magazine is "inserted" into. The first occurrence + of the Magazine + directive in the vchanger configuration file specifies the magazine in bay + 0, the second occurrence specifies the magazine in bay 1, and so on. The + virtual bay is simply a zero-based index into the array of + filesystems/directories defined by Magazine + directives in the vchanger configuration file, and will be + referred to as a "magazine index".

+

The magazine index, or virtual bay, for a magazine is static and + determined solely by the order in which the Magazine + definitions appear in the vchanger configuration file. This + allows assigning integer numbers to the magazines to ease tracking of + multiple magazines. For example, consider an autochanger associated with a + Storage resource + in bacula-dir.conf named "changer1" for which we are using 10 RDX + cartridges as its virtual magazines. The default volume naming scheme used + by the CREATEVOLS command will name the first volume file created on the + first Magazine as + "changer1_0_0", the 23rd volume created on the second Magazine + as "changer1_1_22", and so on. When Bacula later requests a + volume that is on a RDX cartridge that is not currently mounted, this + volume file naming scheme will make it very easy to determine which RDX + cartridge needs to be attached in order to make the requested volume + available.

+

On most systems, filesystems to be used as magazines may be specified by + filesystem UUID, rather than mountpoint directory. This is useful on + systems where udev, Gnome Nautilus, other dbus-enabled automounters, and + etc. are used to automatically mount removable drives whenever they are + attached. Since vchanger is not normally running as root, it makes no + attempt to mount those filesystems. It only queries the system to + determine the current mount point of an already mounted filesystem.

+

Note that there is nothing special about the directories and filesystems + being used as magazines. A directory containing volume files created by + Bacula's native disk storage handling can be used as a vchanger magazine. + Likewise, a directory containing volumes created using a vchanger + autochanger can later be used with Bacula's native disk storage. Also, + individual volume files can be moved between the two. The only stipulation + is that the volume must have the same Media + Type as the bacula-dir.conf Storage + resource that it will be used with. If existing volumes are being moved to + a Storage + resource that has + a different Media + Type, then it will be necessary to manually update the Media + Type for those volumes.

+

4.2. Volume Files

+

A volume file is simply a regular file on one of the defined magazine + directories or file systems. A file cannot be used by Bacula until a + Bacula volume label has been written to it. Bacula supports bulk labeling + of volumes using barcodes. Many tape autochangers have barcode reader + hardware that can read the name of a tape cartridge from a barcode printed + on an adhesive paper label attached to the tape cartridge. The tape + autochanger can be commanded to read the barcodes and list the names of + the tapes it finds in each of its library slots. Bacula's label + barcodes command acquires this information from the tape + autochanger and writes a Bacula volume label to each unlabeled tape, + naming it according to the tape's barcode. Vchanger emulates a barcode + reader by using the volume file's filename as the barcode for that volume.

+

While it is recommended to use the default volume naming scheme + implemented by the CREATEVOLS command, it is not required and volume files + can have any filename. Just keep in mind that vchanger uses the volume + file's filename as its barcode label. This means that the filename must + match the volume label that was written to the file when the volume was + labeled. Volumes cannot be renamed by simply renaming the file to a + different filename. They would also have to have a new Bacula volume label + written to them.

+

4.3. Virtual Slots

+

Each time vchanger is invoked it maps the volume files on all attached + magazines to a virtual slot number. State information kept in the + autochanger's work directory is used to keep volume-to-slot mapping as + consistent as possible when removable disk drives are attached and + detached from the system. Drive state files contain information about the + volume last loaded into a virtual drive and are named 'drive_state-N', + where N is the drive number. Magazine state files contain information + about the magazines that were attached when vchanger was last invoked and + are named 'bay_state-N', where N is the magazine index.

+

Whenever anything happens to change the volume-to-slot mapping, Bacula + must be informed of the change. This is because Bacula tracks the contents + of autochanger slots in its catalog, as it must know which volumes are + available and where they are located in order to decide which volumes + should be assigned to which jobs and which volumes should be loaded into + which drives. Vchanger notifies Bacula when something changes by invoking + bconsole and issuing an update + slots command to cause Bacula to update its catalog info for the + affected autochanger.

+

Note that vchanger is not dependent on the state information kept in an + autochanger's work directory. Vchanger recalculates the current state of + virtual drives, bays, and slots whenever invoked. However, the state + information allows vchanger to only issue the update + slots command when a change is detected that requires it and + allows keeping the volume-to-slot mapping as consistent as possible.

+

4.4. Virtual Drives

+

Bacula treats volumes on a vchanger autochanger in the same way that it + treats tapes in a tape autochanger, by loading the volume it is going to + access into one of the autochanger's drives. Vchanger "loads" a virtual + drive by creating a symlink at a known location in the autochanger's work + directory that points to the volume file being loaded. A virtual drive is + unloaded by deleting that symlink. Vchanger supports a + dynamic and unlimited number of virtual drives. The number of + virtual drives actually used by Bacula will be determined in the Bacula + Storage Director's configuration file by the number of Device + resources assigned to the Autochanger + resource associated with the vchanger autochanger. Additional + virtual drives can be added by adding additional Device + resources to the Autochanger + resource in bacula-sd.conf and requires no further changes to the + vchanger configuration.

+

4.5. Vchanger Commands

+

The LIST command is performed by simply listing to stdout the calculated + slot-to-volume mapping, one line per virtual slot, in the format

+ 
slot:barcode
+

where slot is the virtual slot + number and barcode is the + filename of the volume mapped to that virtual slot. Because slot-to-volume + mapping is kept as consistent as possible, there may be virtual slots that + are empty, (ie. not currently mapped to a volume file). Empty slots will + be listed without a barcode string following the ':'.

+

The LISTALL command is similar to the LIST command except that it lists + drive status in addition to slot status to stdout. The output is in the + format

+ 
type:num:status:barcode
+

where type is 'D' for a drive + or 'S' for a slot, num is an + integer drive number for drives or slot number for slots, status + is 'F' for full or 'E' for empty, and barcode + is the filename of the associated volume file.

+

The LOAD command is performed by creating a symlink in the autochanger's + work directory that points to the volume file mapped to the requested + slot. The symlink is named as the integer drive number of the virtual + drive being loaded. For example, if the autochanger's work directory is + /var/spool/vchanger/changer1 and volume file /mnt/mag/volume1 is mapped to + virtual slot 10, then a LOAD command requesting that slot 10 be loaded + into drive 0 would result in the creation of a symlink named  + /var/spool/vchanger/changer1/0 that points to the file /mnt/mag/volume1.

+

The UNLOAD command is performed by deleting the symlink that was created + for a virtual drive by a previous LOAD command.

+

The LOADED command is performed by printing to stdout the slot number of + the virtual slot currently loaded into the requested drive, or zero if the + drive is not currently loaded.

+

The SLOTS command is performed by printing the current number of virtual + slots to stdout. For each autochanger, vchanger tracks the maximum number + of slots that have ever been simultaneously available on mounted magazines + in the dynamic.conf file in the autochanger's work directory. This is the + number reported by the SLOTS command. The number of slots defined for an + autochanger will increase as needed when multiple magazines are + simultaneously attached, but it will never decrease.

+

The LISTMAGS command is performed by printing one line of status + information for each magazine defined in the vchanger configuration file. + The format of a status line is:

+ 
bay:slots:start:mountpoint
+

where bay is the zero-based + index of the Magazine + line in the vchanger configuration file, slots + is the number of volume files currently existing on the magazine, + start is the starting slot + number of the range of virtual slots mapped to the magazine's volume + files, and mountpoint is the + magazine's directory or current filesystem mount point.

+

The CREATEVOLS command is used to add new volume files to a magazine and + cause Bacula to write volume labels to them.

+

The REFRESH command causes vchanger to refresh the current state of + magazines and virtual drives and issue a update + slots command via bconsole if needed. This command is intended to + be invoked when a magazine filesystem is mounted or unmounted, for example + by an automount script invoked by udev or by the operator after manually + mounting a magazine filesystem.

+

5. Installing vchanger

+

5.1. Installing from Source

+

On most POSIX systems, vchanger can be compiled and installed from source + as follows.

+

Unpack the gzip compressed tar archive.

+ 
[]$ tar -xzf vcahnger-1.0.0.tar.gz
+

Configure the build system and compile + vchanger

+ 
[]$ cd vchanger
+[]$ ./configure
+[]$ make
+

As root, install the executable and + documentation

+ 
[]$ su root
+[]# make install-strip
+

This will install the vchanger executable in + /usr/local/bin, udev automount scripts in /usr/local/libexec/vchanger, and + the documentation in /usr/local/share/doc/vchanger.

+

5.2. Installing from an RPM Package

+

x86_64 RPM packages for RHEL/Centos 6.x and RHEL/Centos 7.x, along with + the GPG signing key, are available for downloading from the vchanger + project page on SourceForge. An RPM install will create the /etc/vchanger + directory to hold autochanger configuration files, the /var/spool/vchanger + directory under which autochanger work directories will be created, and + the /var/log/vchanger directory under which autochanger log files will be + written.

+

The spec files used to create the RPM packages are included in the rpm + directory of the source distribution for those who would like to build an + RPM for other distributions or architectures.

+

5.3. Installing the Windows Version of + vchanger

+

On Windows, vchanger requires at least Windows Server 2008 or Vista and + will not run on earlier versions of Windows. A Windows installer is + available for downloading from SourceForge that will install a x86 or + x86_64 build of vchanger.

+

5.3.1. Installing the Windows Version from + Source

+

The Windows version was developed under Centos + 7.0 using the MinGW-w64 + (gcc-4.9.1) cross-compiler system. On a Linux system with MinGW-w64 + development tools installed, the Windows version can be built as follows:

+

Unpack the gzip compressed tar archive in your home directory.

+ 
[]$ cd ~
+[]$ tar -xzf /path/to/vcahnger-1.0.1.tar.gz
+

Configure the build system and cross-compile + vchanger

+ 
[]$ cd vchanger
+[]$ ./configure --host=x86_64-w64-mingw32 --build=`./config.guess` --prefix=./win32
+[]$ make
+[]$ make install-strip
+

The win32 executable, vchanger.exe, will be in + ~/vchanger/win32/bin and the Windows version documentation in + ~/vchanger/win32/share/doc/vchanger.

+

Building the Windows installer for vchanger requires the makensis + ustility from the NSIS project in addition to MinGW-w64. A shell script + named win32build in the source distribution will configure and build both + 32-bit and 64-bit Windows versions and then run makensis to create a + Windows installer that will install the 32-bit version on 32-bit versions + of Windows or the 64-bit version on 64-bit versions of Windows.

+

6. Preparing Removable Drives

+

6.1. Preparing Drives

+

Preparing removable drives for use by vchanger is fairly straight + forward. All that is needed is a filesystem partition on the removable + drive. Most external USB drives come with a NTFS filesystem installed and + using a GPT partition table. It is recommended that new removable drives + be partitioned and formatted to include a single partition and filesystem + encompassing the entire disk. Any read/write filesystem supported by the + OS may be used.

+

6.1.1. Setting Permissions for the + Magazine Filesystem

+

The Bacula Storage Daemon does not usually run as root. Since vchanger + will be invoked by the Storage Daemon, and so will run as the same user + that it does, permissions for magazine filesystems must be set to allow + read/write access to that user. This can be done by mounting the new + partition somewhere, then setting the appropriate permissions to give + read/write access to the user that the Storage Daemon runs as. It may also + be necessary to configure SELinux or AppArmour to allow the user that the + Storage Daemon runs as to read/write the magazine filesystems.

+

6.2. Determining the Magazine's + Filesystem UUID

+

On most POSIX systems, the blkid utility can be used to view the UUID of + a partition's filesystem.

+

On Windows, a filesystem UUID is known as a Volume Serial Number, (not to + be confused with the manufacturer's hardware serial number). Volume Serial + Numbers, are 8 hex digits with a '-' between the first 4 and last 4 hex + digits. This format differs from the UUIDs used by most POSIX systems, and + is due to Windows storing the Volume Serial Number internally as a 32-bit + binary number. This is not a problem, however, as Linux (and probably most + other POSIX systems) will happily use the Windows Volume Serial Number as + the filesystem UUID, though it is shorter in length. The simplest way to + get the Volume Serial Number is to open a Command Prompt window and issue + a DIR command on the removable drive's drive letter.

+

7. Mounting Removable Disk Drives

+

On Linux and other modern POSIX systems, removable drives are assigned a + device node when they are plugged in, but the OS does not by default mount + the drive partitions. Automounting is often handled by, for example, Gnome + Nautilus, + but this may not suffice for use with daemons, such as the Bacula Storage + Daemon that will normally invoke vchanger. The block storage device + containing the magazine's filesystem partition must, by some means, be + mounted before it can be used by vchanger. Since vchanger will be invoked + by the Bacula Storage Daemon, and will not ordinarily run with superuser + privileges, it does not itself attempt to mount filesystems.

+

7.1. udev and Hot-swappable Drives

+

Udev + is the subsystem that dynamically assigns device nodes to hot swappable + hardware devices when they are attached to a running system and frees + those device nodes when they are detached. In general, there is no + guarantee that a particular piece of hardware will be assigned a known + device node when it is plugged in. The device node that udev assigns will + depend on how many other devices are already attached and could change + every time the hot-swappable device is plugged in.

+

Fortunately, udev provides a way to create aliases to the device nodes it + assigns so that the device can be accessed using the fixed alias, + regardless of the actual device node assigned. With most Linux + distributions, the aliases are symlinks created dynamically by udev in + subdirectories of /dev/disk, and these symlinks point to the actual device + node assigned to the block storage device. In particular, symlinks are + created under /dev/disk/by-uuid such that the symlink name is the UUID of + the partition's filesystem. Consider, for example, a USB removable drive + with a partition containing a ext3 filesystem with UUID + 9667f83c-6150-44c7-b0d4-57564f174b35. When this USB drive is attached, + udev will assign a device node to it's partition and create the symlink + /dev/disk/by-uuid/9667f83c-6150-44c7-b0d4-57564f174b35 pointing to the + actual device node assigned. The device can then be accessed using the + known 'by-uuid' alias without having to discover the actual device node + assigned.

+

7.2. Manually Mounting Removable Drive + Partitions

+

One way to handle mounting and unmounting of removable drive partitions + is for the operator to manually mount the partitions when the removable + drive is attached and manually unmount the partitions before they are + detached. The mounting of magazine filesystems can be simplified by adding + the mounting information for the magazine filesystems to /etc/fstab, + identifying the partition by its filesystem UUID, and assigning the + filesystems in the vchanger configuration file by UUID. For example:

+ 
#/etc/fstab
...
# USB disks for vchanger
+UUID=7b4526c4-d8e9-48ba-b227-f67f855a0dc7 /mnt/vchanger/mag0 ext4 defaults,noauto 1 2
+UUID=a4902c05-e47d-40e0-9db7-b3d03d08c266 /mnt/vchanger/mag1 ext4 defaults,noauto 1 2
+...
#eof

#/etc/vchanger/vchanger.conf
Storage Resource = vchanger
...
Magazine = UUID:7b4526c4-d8e9-48ba-b227-f67f855a0dc7
Magazine = UUID:a4902c05-e47d-40e0-9db7-b3d03d08c266
+#eof
+

The removable drive being used as magazine 0 could them be mounted and + made available with:

+ 
[]# mount /mnt/vchanger/mag0
[]# vchanger /etc/vchanger/vchanger.conf refresh
+

After use, the removable drive can then be removed using:

+ 
[]# umount /mnt/vchanger/mag0
[]# vchanger /etc/vchanger/vchanger.conf refresh
+

It is also possible, when manually mounting magazine partitions, to use + the mountpoint path in the Magazine + directive, rather than the UUID. When a magazine is specified by + path (rather than by UUID), vchanger assumes the magazine is mounted if + that path exists. However, if that directory path exists while the + magazine's partition is not mounted, then that directory will be part of + the underlying filesystem rather than the unmounted magazine partition's + filesystem. For this reason, specifying directory paths in Magazine + directives is only recommended for permanently mounted filesystems. + Filesystems that are not permanently mounted should be specified by UUID. +

+

7.3. Using udev To Mount Removable Drive + Partitions

+

Udev + responds to kernel messages to enable naming and handling of devices as + they are attached and detached from the system using a rule-based + approach. Rule files stored in /etc/udev/rules.d and /usr/lib/udev/rules.d + enable tailoring the naming and handling of hardware devices. Udev rules + make it possible to run short scripts in response to device events. With + the appropriate rules and the helper scripts provided with vchanger, the + attachment and detachment of removable disk drives used as vchanger + magazines can be made into a plug-n-play operation.

+

The vchanger-genudevrules + script will scan all vchanger configuration files in /etc/vchanger and + output to stdout the udev rules needed for each magazine that is specified + by filesystem UUID. These rules configure udev to execute scripts whenever + the partition with that filesystem UUID is attached or detached. The + scripts are included in the scripts directory of the vchanger source and + are usually installed into the /usr/libexec/vchanger directory.

+

The rule that matches when the device is attached invokes /usr/libexec/vchanger/vchanger-launch-mount.sh. + This is a very simple script with the sole purpose of lanching the + /usr/libexec/vchanger/vchanger-mount-uuid.sh script as a separate, + independent process. This is because udev does not invoke scripts in a + true shell and the scripts it invokes must execute very quickly and + without error The vchanger-mount-uuid.sh + script is supplied with a single argument, the UUID of the partition being + attached. If there is an fstab entry for the filesystem UUID, then the + partition is mounted using the mount point and mount options specified in + /etc/fstab. Otherwise, the partition is mounted at MOUNT_DIR/{uuid}, where + MOUNT_DIR is defined in a default parameter file named + /etc/default/vchanger (or /etc/sysconfig/vchanger). The + /etc/default/vchanger file may also define MOUNT_OPTIONS to be the mount + options that should be passed to the mount command via the -o flag. Note + that the same MOUNT_OPTIONS will be passed to the mount command for every + magazine file system. If there are magazine filesystems that require + different mount options, then they will have to be defined in /etc/fstab. + Finally, the script ends by invoking vchanger with the REFRESH command to + update state and issue a "update slots" command to Bacula via bconsole.

+

After adding or changing Magazine directives in a vchanger configuration + file, configure automounting through udev by:

+ 
[]# vchanger-genudevrules >/etc/udev/rules.d/96-vchanger.rules
[]# udevadm control --reload-rules
+

7.4. Using autofs To Mount Removable Drive + Partitions

+

The autofs daemon provides a way to + mount and unmount the magazine partitions on-the-fly as they are accessed. + This eliminates the need for manual mounting, but in a different way than + when using udev rules. autofs works by watching for accesses of a + particular path and mounting the device at that path on an as-needed + basis, then unmounting after an idle period. When using autofs to mount + the magazine partitions, the Magazine + directives in the vchanger configuration file will specify the + path to the mountpoint, rather than the filesystem UUID. Specifying paths + for Magazine directives + does not present a problem in this case, since autofs creates and deletes + the path dynamically as it mounts and unmounts the filesystem. For all + practical purpose, a mountpoint path controlled by autofs can be treated + as if it were permanently mounted.

+

An automount map file for use with vchanger is given below.

+ 
# /etc/auto.vchanger
+*          -fstype=auto,rw,sync       :/dev/disk/by-uuid/&
+# eof
+

Notice that 'sync' is specified in the flags that autofs will pass to the + mount command. This will turn off write caching and force all writes to + the magazine's filesystem to be written immediately to disk. Though it + reduces write performance, it helps to reduce the chance of data loss when + a removable drive is detached following a backup. Much better write + performance can be had by not specifying the sync option and being careful + not to unplug removable drives until after autofs unmounts them.

+

A line is then added to the /etc/auto.master file to tell autofs to pull + in the new auto.vchanger configuration:

+ 
# /etc/auto.master
+# ...
+/mnt/vchanger      /etc/auto.vchanger        --timeout=30
+# eof
+

After restarting the autofs daemon, whenever a file or directory with a + full path beginning with '/mnt/vchanger' is accessed, autofs will search + the map defined in the /etc/auto.vchanger file for a key matching the path + being accessed. In this case, the only key in /etc/auto.vchanger is the + wildcard '*', meaning any path name beginning with '/mnt/vchanger' will + match. Autofs then automatically mounts the device mapped to the wildcard + key at the path being accessed. The /etc/auto.vchanger map file specifies + the device to be mounted as /dev/disk/by-uuid/&. The '&' is + substituted for the key value. For example, when a program attempts to + access /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35 + (or any files or directories below it), the autofs daemon will look at + the auto.vchanger map for the key 9667f83c-6150-44c7-b0d4-57564f174b35 + and discover that it should mount + /dev/disk/by-uuid/9667f83c-6150-44c7-b0d4-57564f174b35 at + /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35 with mount options + '-fstype=auto,rw,sync'. After a period of 30 seconds of no activity, + autofs will automatically unmount the device.

+

Always make sure autofs is working properly + before continuing with setting up vchanger. If using the above autofs + config files, when you plug in a USB drive with filesystem UUID of, say, + 9667f83c-6150-44c7-b0d4-57564f174b35, you should be able to list its + contents with the command

+ 
[]# ls /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35
+

The Magazine directive in the vchanger + configuration file for the above example partition would be:

+ 
Magazine = /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35
+

7.5. Mounting Removable Drives On Windows

+

Microsoft Windows operating systems normally automount removable drive + partitions with recognized file systems. By default, the mountpoint for a + partition will be a drive letter (ie. E:). Unlike POSIX operating systems, + where '/' is the root of the single directory tree, Windows operating + systems use a multi-root directory structure where drive letters (and + network UNC base names) represent the roots of multiple, distinct + directory trees. When a removable drive is plugged in for the first time, + assuming the drive has a single partition, its partition will be mounted + at the next available drive letter. Windows remembers the drive letter + assignment for a partition so that it will be mounted at the same drive + letter when it is later re-attached, unless the drive letter is already + being used for another partition, in which case it will be mounted at the + next available drive letter. Note that it is not possible to assign the + same drive letter to two different removable drives simultaneously.

+

It is also possible, however, to mount a volume at a (empty) subdirectory + in another directory tree, as long as the volume mounted at the root of + that other directory tree is a NTFS volume. In fact, only the volume from + which Windows boots and volumes containing a virtual memory storage file + even require a drive letter at all. For removable drives, the drive letter + assignment can be deleted altogether and the partition always auto-mounted + at a directory in an NTFS directory tree. It should be noted that only the + mount point directory must be on an NTFS volume. The partition being + mounted may have a FAT32 file system or any other file system for which + there is a file system driver installed. See “Assign + a mount point folder path to a drive” for instructions on assigning + mountpoints for removable drive partitions. Like with drive letters, it is + not possible to assign the same mountpoint to more than one drive.

+

On Windows, magazine partitions should always be specified by UUID + (Volume Serial Number). This ensures that vchanger will be able to find + the partition's mountpoint without prior knowledge of which drive letter + or mountpoint Windows has currently assigned to the drive.

+

8. Configuring vchanger

+

Each vchanger autochanger is defined by a configuration file. Multiple + autochangers may be defined as long as each is given a unique name, its + own unique work directory, and its own unique configuration file. By + default, vchanger configuration files are placed in the /etc/vchanger + directory. The configuration files must be given permissions that + allow the user that the Bacula Storage Daemon runs as to have read access.

+

A vchanger configuration file consists of + keyword = value pairs. Comments are defined by a '#' character, and cause + text from the '#' until the next newline character to be ignored. Values + including whitespace or special characters must be enclosed in single or + double quotes. Special characters, including the quote character, + appearing inside of the quoted value must be escaped by prepending with a + '\' character. The following keywords are defined for an autochanger + configuration file:

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
+

Storage Resource

+ 		+

[Required] The name of the Storage resource, defined in the + Bacula Director configuration file, that is associated with this + autochanger.
+ Default: none

+
+

User

+ 		+

User to run as when vchanger is invoked by root. This user must + have read/write access to the work directory, magazine + directories, and volume files and should be the same user that the + Bacula Storage Daemon runs as.
+ Default: bacula

+
+

Group

+ 		+

Group to run as when vchanger is invoked by root. This group must + have access to the work directory, magazine directories, and + volume files and should be the same group that the Bacula Storage + Daemon runs as.
+ Default: tape

+
+

Work Dir

+ 		+

The directory where this autochanger will store virtual drive and + magazine state information and create symlinks to its volume + files.
+ Default: /var/spool/vchanger/{Storage Resource}

+
+

Logfile

+ 		+

Path to the logfile for this autochanger.
+ Default: /var/log/vchanger/{Storage Resource}.log

+
+

Log Level

+ 		+

The level of detail being logged. An integer value from 0-7 is + expected, where higher values increase logging. The levels + correspond to 'LOG_EMERG' through 'LOG_DEBUG' as defined for the + syslog() system call. See man 2 syslog for possible values.
+ Default: 3

+
+

bconsole

+ 		+

The path to the bconsole binary that vchanger will invoke to + issue 'update slots' and 'label barcodes' commands to Bacula. To + disable interaction with Bacula, set to the empty string.
+ Default: /usr/sbin/bconsole

+
+

bconsole config

+ 		+

The path to the configuration file to use when invoking bconsole.
+ Default: /etc/bacula/bconsole.conf

+
+

Default Pool

+ 		+

The default pool in which to add new volumes created by the + CREATEVOLS command.
+ Default: Scratch

+
+

Magazine

+ 		+

[Required] Defines either the path to a directory or the UUID of + a filesystem partition (prepended by the string “UUID:”) that is + to be used as a magazine containing volume files . The magazine + directive assigns a directory or partition to this autochanger. + This directive may appear multiple times to assign multiple + magazines.
+ Default: none

+
+

9. Initializing New + Magazines

+

After storage for a new magazine has been prepared, + it must be defined as an autochanger magazine. This is accomplished by + adding a Magazine + directive to the vchanger configuration file. For removable storage, the Magazine directive + should specify the filesystem UUID (or the mountpoint path if using + autofs). If a directory on permanently mounted fixed-disk storage is being + used as a magazine, then the Magazine + directive should specify the directory path. In either case, the + filesystem or directory must by writable by the user that Bacula Storage + Daemon runs as. The LISTMAGS vchanger command can be used to determine + that the magazine has been defined.

+

Once defined as an autochanger magazine, it is necessary to create volume + files on the magazine. While this can be accomplished manually by creating + empty files on the magazine and then labeling them from within bconsole + using the label + barcodes command, to make + adding volume files to a magazine easier and to facilitate a consistent + naming scheme, vchanger implements the CREATEVOLS command as:

+ 
vchanger config_file CREATEVOLS mag_bay count [start] [--pool=pool_name] [--label=prefix_string]
+

CREATEVOLS provides an easy way to add new volume files to a magazine and + label them into an appropriate pool. Volume files can be added to a + magazine at any time. Appendix A covers details of the CREATEVOLS + command.

+

10. Testing vchanger

+

Vchanger may be tested by running it from the command line. You must + either invoke vchanger as root or else as the user:group specified in the + vchanger configuration file, (which must be the same user:group that the + Bacula Storage Daemon runs as). If invoked as root, vchanger will switch + users to run as the user:group specified in the vchanger configuration + file given in the first parameter.

+

For example purposes, an autochanger using vchanger with USB external + drives will be designed step by step. Initially, two USB drives will be + initialized. For each of the two drives, the output from the dmesg command + is used to determine the assigned block device, and the blkid command used + to determine the UUID of its ext4 filesystem. A vchanger configuration + file is defined with Magazine directives assigning the empty USB drive + partitions to an autochanger named vchanger-1.

+ 
# /etc/vchanger/vchanger-1.conf
+Storage Resource = vchanger-1
User = bacula
Group = tape
Magazine = UUID:9667f83c-6150-44c7-b0d4-57564f174b35
+Magazine = UUID:5039284a-4312-57d1-92c4-354710032c79
+#eof
+

This defines an autochanger associated with a bacula-dir.conf Storage + resource named vchanger-1, with the Bacula Storage Daemon running as user + bacula:tape, and using two filesystems on removable USB drives as its + magazines. The filesystems will be mounted using udev, and the automount + scripts in the scripts directory of the vchanger source have been + installed to /usr/libexec/vchanger and the vchanger-genudevrules script + installed to /usr/bin. The udev rules needed to automount the magazine + filesystems can be generated and added to the udev rules with:

+ 
[]# vchanger-genudevrules >/etc/udev/rules.d/96-vchanger.rules
[]# udevadm control --reload-rules
+

A directory is created under which udev will mount the filesystems. The + filesystems will be mounted at subdirectories of this directory using the + filesystem UUID string as the subdirectory name.

+ 
[]# mkdir /mnt/vchanger
[]# chown bacula:tape /mnt/vchanger
[]# chmod 750 /mnt/vchanger
[]# echo "MOUNT_DIR=/mnt/vchanger" >/etc/sysconfig/vchanger
[]# echo "MOUNT_OPTIONS= >>/etc/sysconfig/vchanger
+

Now, attaching the USB drives should cause udev to invoke the + vchanger-mount-uuid.sh script to mount the filesystems as subdirectories + of the directory defined by the MOUNT_DIR variable specified in + /etc/sysconfig/vchanger (or /etc/default/vchanger).

+ 
[]# ls -1 /mnt/vchanger
+9667f83c-6150-44c7-b0d4-57564f174b35
+5039284a-4312-57d1-92c4-354710032c79
+
+

The owner and permissions must be set for the new filesystems in order to + give read/write access to the user that the Bacula Storage Daemon runs as:

+ 
[]# chown bacula:tape /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35
+[]# chmod 750 /mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35

+][# chmod 750 /mnt/vchanger/5039284a-4312-57d1-92c4-354710032c79
+
+

The Storage resource that this autochanger is associated with is defined + in bacula-dir.conf as:

+ 
# /etc/bacula/bacula-dir.conf
...
# vchanger autochanger vchanger-1
+Storage {
+  Name = vchanger-1
+  Address = 192.168.1.9
+  SDPort = 9103
+  Password = "password"
+  Device = usb-vchanger-1
+  Media Type = File
+  Autochanger = yes;
+  Maximum Concurrent Jobs = 20
+}
+...
+#eof
+

The Device resource pointed to by the Storage resource is defined in + bacula-sd.conf as:

+ 
# /etc/bacula/bacula-sd.conf
...
# vchanger autochanger vchanger-1
+Autochanger {
+  Name = usb-vchanger-1

+  Maximum Concurrent Jobs = 1
+  Archive Device = "/var/spool/vchanger/vchanger-1/1"

+...
+#eof
+

After detaching both of the USB drives, list the status of the magazine + partitions currently in use by invoking (as root):

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf listmags
+0:::
1:::
+

The output from the LISTMAGS + command shows that + neither of the magazine partitions is mounted, which is correct, since + neither of the two USB drives are attached. After attaching the USB drive + having the partition we defined in the first + Magazine directive, the output is:

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf listmags
+0:::/mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35
+1:::
+

The output from the LISTMAGS command + now shows that the first defined magazine is mounted, but it has no + volumes. We can now add some + volumes with:

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf createvols 0 2
+creating label 'vchanger-1_0_0'
+creating label 'vchanger-1_0_1'
+Created 2 volume files on magazine 0
+
+

Now the output from a LISTMAGS + command:

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf listmags
+0:2:1:/mnt/vchanger/9667f83c-6150-44c7-b0d4-57564f174b35
+1:::
+

will show that the first defined magazine is mounted and has 2 volumes + mapped to virtual slots 1-2. We can issue the LIST command to see what + volumes the vchanger-1 autochanger has in its virtual slots.

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf list
+1:vchanger-1_0_0
2:vchanger-1_0_1
+

This shows that two volume files are in slots 1 and 2. We can use + bconsole to see what Bacula thinks the autochanger status is.

+ 
[]# echo "status slots storage=vchanger-1 drive=0" | bconsole

+

This shows that the CREATEVOLS + command has created two volume files on the first magazine and has + successfully labeled them using the label barcodes command via + bconsole.

+

Now attach the second USB drive and add some volumes to it using:

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf createvols 1 3
+creating label 'vchanger-1_1_0'
+creating label 'vchanger-1_1_1'

+
+

Let's now examine what happens when a volume file is "loaded" into a + virtual drive.

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf load 3 /dev/null 0
+[]# ls -l /var/spool/vchanger/vchanger-1
+lrwxrwxrwx 1 bacula tape 29 Mar  1 16:46 0 -> /mnt/vchanger/5039284a-4312-57d1-92c4-354710032c79/vchanger-1_1_0
+-rw-r----- 1 bacula tape 21 Mar  1 16:46 bay_state-1
+-rw-r----- 1 bacula tape 30 Mar  1 16:46 drive_state-0
+
+

The LOAD command created a symlink named '0' in the autochanger's work + directory that points to the file 'vchanger-1_1_0' in the filesystem + mounted at /mnt/vchanger/5039284a-4312-57d1-92c4-354710032c79, the volume + file that is mapped to virtual slot 3. The symlink named '0' is this + autochanger's drive 0. Notice that the path to this symlink was defined in + bacula-sd.conf as the Archive + Device for this autochanger's drive 0. When Bacula opens th the + symlink for reading or writing, it will actually be opening the volume + file that the symlink points to. 

+

The LOADED command can be used to check the status of a drive.

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf loaded 0 /dev/null 0
3
[]# vchanger /etc/vchanger/vchanger-1.conf loaded 0 /dev/null 1
0
[]# vchanger /etc/vchanger/vchanger-1.conf loaded 0 /dev/null 13
0
+
+

The first command shows that drive 0 is loaded from slot 3. The zero + result of the second command shows that drive 1 is empty. The last line + shows that drive 13 is also empty. Although only drive 0 and drive 1 were + defined for this autochanger in bacula-sd.conf, vchanger commands will + operate on an unlimited number of virtual drives without requiring any + change in the vchanger configuration file. However, Bacula will only make + use of virtual drives defined by a Device + resource in bacula-sd.conf.

+

Finally, a virtual drive is unloaded using the UNLOAD command.

+ 
[]# vchanger /etc/vchanger/vchanger-1.conf unload 3 /dev/null 0
[]# ls -l /var/spool/vchanger/vchanger-1
+-rw-r----- 1 bacula tape 21 Mar  1 16:46 bay_state-1
{}# vchanger /etc/vchanger/vchanger-1.conf loaded 0 /dev/null 0
0
+

The virtual drive is unloaded by removing its corresponding symlink.

+

It is also possible to define mountpoints and mount options for the + magazine filesystems, (by UUID), in /etc/fstab. When the + vchanger-mount-uuid.sh script is invoked by udev, it will check for the + existence of an fstab entry for the magazine filesystem's UUID, and if it + exists will mount using the /etc/fstab entry rather than using the UUID as + the name of a subdirectory of the MOUNT_DIR directory defined in + /etc/sysconfig/vchanger.

+

11. Configuring Bacula To Use The + Autochanger

+

The virtual autochanger must be defined in Bacula by adding Autochanger and Device resources to Bacula's configuration + files.

+

11.1. Configuring the Bacula Storage Daemon

+

To configure the Bacula storage daemon (bacula-sd), add an Autochanger + resource and associated Device resource(es) to bacula-sd.conf. An + example of an autochanger with 2 virtual drives is:

+ 
# /etc/bacula/bacula-sd.conf
+# ...
+#----  local virtual autochanger with USB drive "magazines"
+Autochanger {
+  Name = usb-changer
+  Device = usb-changer-drive-0
+  Device = usb-changer-drive-1
+  Changer Command = "vchanger %c %o %S %a %d"
+  Changer Device = "/etc/vchanger/vc1.conf"
+}
+#---  drive 0 of the usb-changer autochanger
+Device {
+  Name = usb-changer-drive-0
+  DriveIndex = 0
+  Autochanger = yes;
+  DeviceType = File
+  MediaType = File
+  ArchiveDevice = /var/spool/vchanger/vc1/0
+  RemovableMedia = no;
+  RandomAccess = yes;
+}
+#---  drive 1 of the usb-changer autochanger
+Device {
+  Name = usb-changer-drive-1
+  DriveIndex = 1
+  Autochanger = yes;
+  DeviceType = File
+  MediaType = File
+  ArchiveDevice = /var/spool/vchanger/vc1/1
+  RemovableMedia = no;
+  RandomAccess = yes;
+}# ...
+# eof
+

In the Autochanger + resource, the Changer Device + value is the path to the vchanger configuration file for this autochanger. + The Changer Command value is the + command that Bacula will execute when it needs the autochanger to perform + some function, (like loading a volume). Here, we have installed vchanger + in /usr/bin, and Bacula is going to pass the Changer + Device value (the path to the vchanger configuration file) in + parameter 1, the API command (load, unload, etc) in parameter 2, the slot + number for the command in parameter 3, the Archive + Device value from the Device + resource that has a Drive Index value + equal to the drive index for the command in parameter 4, and the drive + index for the command in parameter 5.

+

11.2. Configuring the Bacula Director

+

The Bacula Director is configured to use the virtual autochanger in + exactly the same way as it would be configured for a tape autochanger.

+ 
# /etc/bacula/bacula-dir.conf
+# ...
+# Local USB drive virtual autochanger
+Storage {
+  Name = vchanger-1   # same as 'Storage Resource' in the vchanger config file
+  Address = sd-server-address
+  Password = "secret_password"
+  Device = usb-changer  # name of the Autochanger resource in bacula-sd.conf
+  Media Type = File
+  Autochanger = yes;
+}
+# eof
+

Appendix A. vchanger Commands

+

A.1. LIST Command

+

Bacula + issues this command to an autochanger to list to stdout the “barcode + labels” of volumes in the autochanger's slots. Many tape autochanger + robots have barcode readers such that tapes can be affixed with an + adhesive barcode label that identifies the tape. This allows Bacula to + automate the process of creating volume labels by utilizing the + autochanger's barcode reader. Vchanger emulates barcodes for the volumes + in a virtual autochanger's slots by listing the names of volume files + mapped to each virtual slot. The empty string is listed for each slot + corresponding to an empty slot (a slot that is not currently mapped to a + volume file).

+

A.2. LISTALL Command

+

It is not clear that Bacula currently uses this command internally, and + it is not specified in the Bacula + Autochanger Interface documentation. Nevertheless, it is implemented + in Bacula's mtx-changer script since version 5.1.0 and is used by some + web-based admin utilities, so has been implemented in vchanger. This + command is similar to the LIST command except that it also lists current + drive status in addition to slot status.

+

A.3. LOAD Command

+

The load command is used to “load” a volume + file from a virtual slot into a virtual drive. A tape autochanger does + this by physically moving the tape located in the requested library slot + into a tape drive. Bacula reads and writes volume data from/to the tape + drive's device file. With vchanger, a filesystem symlink at a known path + is used as a virtual drive in place of a tape drive's device file. A + volume file is then loaded by making the target of that symlink point to + the volume file mapped to the requested slot.

+

Parameter 3 gives the autochanger slot number + of the volume to load. Parameter 4 gives the path to the device that + Bacula will read/write and is ignored by vchanger. Parameter 5 gives the + drive number of the virtual drive that the volume is to be loaded into.

+

A.4. LOADED Command

+

This command is issued to determine which + slot, if any, is loaded into a drive. If a drive is loaded, then the + virtual slot number corresponding to the loaded volume file is written to + stdout. If the drive is not loaded, the string “0” is written to stdout to + inform Bacula that the drive is not loaded.

+

A.5. SLOTS Command

+

This + command simply prints to stdout the maximum number of volume files that + the autochanger has ever had simultaneously available. For example, if 6 + USB drive filesystems are assigned as the autochanger's magazines, each + with 10 volume files, and the maximum number of USB drives that were ever + simultaneously attached is 3, then the SLOTS command will return 30. If + more storage is needed at some point and 4 of the USB drives are + simultaneously attached, then a SLOTS command will return 40. Bacula + issues this command to determine how many slots an autochanger has.

+

A.6. UNLOAD Command

+

Bacula issues this command to unload a volume + from a drive and move it back into a library slot. Vchanger accomplished + this by deleting the virtual drive's symlink.

+

A.7. CREATEVOLS Command

+

This is an extended command that is not + part of the Bacula +Autochanger + Interface API, and is + used to add volume files to a magazine filesystem and cause them to be + labeled with a Bacula volume label. The format of this command is

+ 
vchanger config_file createcols mag_ndx count [start_num] [--label=prefix] [--pool=pool_name]
+

where:

+ + + + +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + +
+

config_file
+

+ 		+

Path to the autochanger's configuration file.
+

+
+

mag_ndx
+

+ 		+

The zero-based index of the magazine where volume files are to be + created. The index refers to a Magazine directive in the + configuration file specified by config_file, where 0 is the first + Magazine directive, 1, is the second Magazine directive, etc.
+

+
+

count

+ 		+

The number of volume files to create.

+
+

start_num

+ 		+

The lowest integer to append to the prefix string when forming + unique volume file names. The default is -1. A negative value + causes  the uniqueness number appended to the prefix to be + greater than the currently highest number used for file names + beginning with the given prefix.

+
+

prefix

+ 		+

An optional prefix string used in naming the created volume + files. The default prefix string is the autochanger's name + concatenated with '_' plus the magazine index number.

+
+

pool_name

+ 		+

The name of the pool into which created volumes should be + labeled. The default is "Scratch".

+
+

When new empty volume files are added, vchanger will issue a label + barcodes command to Bacula via bconsole to cause Bacula to write + volume labels on the new volume files. Adding volumes to a magazine will + change the virtual slot to volume mapping and may increase the + autochanger's slot count (the value returned by the SLOTS command). For + this reason, vchanger will also issue the update + slots command to Bacula whenever new volume files are added.

+

A.8. LISTMAGS Command

+

This is an extended command that is not part of the Bacula +Autochanger + Interface API, and is used to list status information about the + autochanger's assigned magazines. The format of this command is

+ 
vchanger config_file listmags
+

where:

+ + + + + + + + +
+

config_file

+ 		+

Path to the autochanger configuration file

+
+

The contents of each magazine bay are written + to stdout, one line per bay. The format of an output line is:

+ 
mag_ndx:count:start_slot:mountpoint
+

where:

+ + + + + + + + + + + + + + + + + + + + +
+

mag_ndx

+ 		+

The zero-based index of the magazine

+
+

count

+ 		+

The number of volume files on the magazine

+
+

start_slot

+ 		+

The beginning of the ranges of contiguous virtual slots mapped to + the magazine's volume files.

+
+

mountpoint

+ 		+

The mountpoint/directory of a mounted magazine, else blank if not + mounted.

+
+

A.9. REFRESH Command

+

This is an extended command that is not part of the Bacula Autochanger + Interface API, and is used to instruct vchanger to scan attached magazines + and recalculate the virtual-slot-to-volume-file mapping, sending an update slots + command to Bacula if any changes are detected.
