Re: [Bacula-users] Bacula-SD hang using IBM Ultrium 3581 Library
I was using unmount from bconsole to unmount the tape. It was not releasing it. That is what is confusing me. But your saying it should. So its even more perplexing now. Release seems to do what I want. It unmounts the tape, and releases the drive. But the word" unmount" seems more intuitive to me than "release".

The difference is that 'umount' unloads the tape and then releases the
drive for use by other programs. 'release' only releases the drive and
informs the SD of the fact that it has to ensure proper tape
positioning when it starts using the tape again.
Your original problem seems to be that you didn't notice you have to
mount the storage after manually unmounting it. Bacula does not send a
reminder mail in these cases, because the operator is expected to know
if the tape was manually unmounted :-)
So, in general: If you unmount a storage device, you have to mount it
again. The current status is, as stated, easily checked with the 'sta
sd' command.

Re: [Bacula-users] Bacula-SD hang using IBM Ultrium 3581 Library
Thanks Blake,
You are correct, it seems when I run an unmount, the drive goes into this
state
Jobs waiting to reserve a drive:
3604 JobId=25 device "Drive-0" (/dev/nst0) is BLOCKED due to user
unmount.
Device status:
Autochanger "Autochanger" with devices:
"Drive-0" (/dev/nst0)
Device "FileStorage" (/tmp) is not open.
Device "Drive-0" (/dev/nst0) is not open.
Device is BLOCKED. User unmounted.
Drive 0 status unknown.
If i restart the bacula-sd daemon, the status is now
Device status:
Autochanger "Autochanger" with devices:
"Drive-0" (/dev/nst0)
Device "FileStorage" (/tmp) is not open.
Device "Drive-0" (/dev/nst0) is not open.
Drive 0 status unknown.
So that appears to be the problem. And my next question is, "release" is
the proper way to unmount a tape from the drive? It appears to work, I'm
just trying to understand the difference. Thanks a lot

Re: [Bacula-users] Bacula-SD hang using IBM Ultrium 3581 Library
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

[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

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
