Some time ago I wrote a shell script based on the disk-changer script and a howto describing my experiences using USB hard drives as "magazines" for a virtual autochanger on Linux. Someone (Brian DeRocher?) put it up on the Bacula wiki last year at http://wiki.bacula.org/doku.php?id=removable_disk. Since then, I ran into some limitations. The lack of virtual drive state info could cause problems when magazine disks were swapped while a virtual drive was "loaded". Also, it provides no way to define a single autochanger that can make use of simultaneously attached disk drives, as for example, a SATA hot-swap bay. As a result, I decided to write a C/C++ program to replace the script.
The GPLv2 source is available at http://sourceforge.net/projects/vchanger/ or by anonymous svn at https://vchanger.svn.sourceforge.net. There is also a 32-bit Win32 installer. The Win32 version uses juntion points and seems to work on XP, at least from the command line. Only one person besides me has used it thus far, so use at your own risk. However, I have been using it for a few months with Bacula 2.4.2 through 2.4.4 running on a Centos 5.2 xen PV domU. (I run Bacula SD and DIR in a dedicated VM on a Linux HA cluster, though it doesn't yet fail-over completely automatically.) I have also tried it on Fedora 8, 9, and 10. The latest version has been in use on the Centos domU for about a week. A Howto in HTML is included with the source, describing how to setup a multi-drive multi-magazine autochanger for Bacula and get automounting of the magazine drives working using udev and autofs.
