So I've had some time to test a few things, and it looks like this is the command that Bacula is sending to see which tape is loaded:
/var/lib/bacula/mtx-changer /dev/sg1 loaded 0 /dev/nst0 0 And, assuming it answers with 12 for slot 12, it ejects the tape using: /var/lib/bacula/mtx-changer /dev/sg1 unload 12 /dev/nst0 0 That seems to work okay, except that Bacula sort of stumbles around afterwards, during the next backup or restore. I've copied part of the log below, but it basically sits there for 5 minutes, until it times out I'm guessing, before it realizes that the tape has been ejected. It then times out for another 5 minutes before it tries to load the tape it needs. So, it looks like it would still be preferable to run some command inside Bacula to eject the tape so that it knows about the ejection, rather than going through the external script. This might be a question for the developers, but is there a simple way to do that? I'm still combing the manual, but haven't found anything relevant yet.

Actually, as a result of my testing last week with umount, my weekend backups didn't run; umount only logically unmounted the tape, and then Bacula sat there waiting for someone to manually (logically) remount the tape. And the manual actually says: If you have an autoloader, the mount command will not cause Bacula to operate the autoloader. Which is, I guess, what I need. Bacula is operating the autoloader for the actual backup, it just keeps the tape in the drive when the backup is finished. It looks like it's calling a program, mtx-changer, to do the actual magic, so I'm going to experiment with that once my weekend backups have completed. --Jeremy -----Original Message----- From: Ryan Novosielski [mailto:[EMAIL PROTECTED] Sent: Monday, September 11, 2006 10:21 To: Jeremy Koppel Subject: Re: [Bacula-users] Autoloader: Replace tape in magazine after backups complete? Those aren't commands. Commands are those that appear in the list when one types "help." Try 'umount' and see what the next step in the script should be. All you're looking to do is write a sequence of console commands -- no different than running them at the console. If you don't know what the console commands are, read the manual.
