If you run a "status storage" when this is occurring, I believe you will see
that the drive is unmounted and offline by user. Mounting a tape, or instead
using the "release" command to unmount tapes should solve your problem if this
is the case.

Subject: [Bacula-users] Bacula-SD hang using IBM Ultrium 3581 Library
Hello,
I'm having a peculiar problem with an IBM Ultrium 3581 autochanger and the SD
daemon. I have to restart the SD daemon after I unmount a tape, or the next
job hangs and never starts.
We currently have a single LTO2 drive in the library, and are running Bacula
2.2.5 on a Redhat Enterprise Linux 4 update 5 IBM server. I ran all the btape
tests, including the multiple tape test for autochangers, and they all worked
flawlessly. Not a single problem or error reported. I am able to use the mtx
script and mt successfully as well. Mtx reports all the proper tapes in the
library, and I can mount a tape and WEOF and REWIND it using mt. Things look
great at this point. Next, I ran "label barcodes" and it labeled all the tapes
in the library properly. Again, no problems. I decided at this point to
modify the "Full OS Set" backup for our environment and run some tests. I can
successfully run the backup the first time. It pulls a tape from the proper
pool inside the library, backup works. But if I unmount the tape in bconsole,
and try and run the same backup again, it hangs. Nothing happens. I have
waited several hours and nothing ever times out. I finally have to cancel the
job manually. I discovered that by restarting bacula-sd that I can then re-run
the job immediately without any problems.
I'm not sure what could be causing this, or how to even troubleshoot. Things
seem to work great during all tests and doing a backup, Bacula just doesn't
like it when I unmount a tape manually.
Could someone offer some advice or debugging steps I could take to figure this
out? Below is a copy of my bacula-sd.conf file. I can post other config files
if I need to. Thanks
Jay
