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
