Re: [Bacula-users] Mounting autochanger
No, I never pick the right one. Nor do I try. I don;t want to have to think about it. I want Bacula to do the work :) I never umount an autochanger but at times I do use the release command. I have to say that a lot of these problems with bacula and autochangers have been fixed recently but to take advantage of these fixes you need the latest beta which is 2.1.20.

Re: [Bacula-users] Mounting autochanger
I use umount to unload a tape that is in the tape drive. Is this not the right way to do this? I am not sure what version added this command but release does the same job for autochangers but it does not cause the need to mount. I believe the difference is umount also releases the drive from bacula's control where release only unloads the tape in the drive.

Re: [Bacula-users] Mounting autochanger
When I go over to the co-lo to change tapes, I go into bconsole and umount the autochanger. Then I eject the magazine from the autochanger's front panel, replace the tapes, shove the magazine back in and wait for the autochanger to stop doing whatever mysterious thrashing it does, then I update slots and mount. This works, and works a whole lot more cleanly than the equivalent procedure used to work under 1.39 (I am on 2.02 now). Should I be doing this a different way?

Re: [Bacula-users] Mounting autochanger
This works, and works a whole lot more cleanly than the equivalent procedure used to work under 1.39 (I am on 2.02 now). Should I be doing this a different way? This is ok. The other method avoids having to mount. Just release each drive that has a tape in it from the changer than you can change the magazines and wait till the auto loader has finished performing an inventory of the tapes and finally an update slots. I have executed the update slots on my changer before the inventory has finished and in my case it waits till the changer is done and then does the command. I am not sure if this happens on all changers though. I have an exabyte Magnum224 with 2 LTO2 drives.

I am not sure if this happens on all changers though. I have an exabyte Magnum224 with 2 LTO2 drives. John I hate getting surprised by commands like this. So I looked at the current docs at http://www.bacula.org/rel-manual/index.html. The only mentions of release don't have anything to do with this command. So I figure it must be in the section for bconsole. Wait, bconsole isn't mentioned in the index either. Ah, maybe under Console Index. Yep, there it is. release This command is used to cause the Storage daemon to rewind (release) the current tape in the drive, and to re-read the Volume label the next time the tape is used. release storage=storage-name After a release command, the device is still kept open by Bacula (unless Always Open is set to No in the Storage Daemon's configuration) so it cannot be used by another program. However, with some tape drives, the operator can remove the current tape and to insert a different one, and when the next Job starts, Bacula will know to re-read the tape label to find out what tape is mounted. If you want to be able to use the drive with another program (e.g. mt), you must use the unmount command to cause Bacula to completely release (close) the device.
