I have a CentOS 5 system, running Bacula-2.2.4 with MySQL database, and
Exabyte VXA-320 tape drive 1x10 1U autoloader.
I have a pool called "cycle", with a few tapes, and max volume duration
setting of 35 days. So, after this time expires, the previous tape will be
marked "used" although not full yet, and the oldest tape in the pool will be
recycled.
However, the new tape won't be mounted properly, after the old tape had
expired. This is what happens:

=====
Finally, typing commands
- release
- mount
makes the tape usable to bacula.
This has happened now at least 3 times, when the tape has expired. But I've
seen no problem running backups to other pools meanwhile, which requires the
autoloader to change tapes anyway.
I have an idea that this may have started after I changed
AlwaysOpen = yes;
to
AlwaysOpen = no;
in sd conf a few months ago. But it was really necessary, since I don't want
to have tapes being mounted all the time (a couple of sudden power losses
have ruined unnecessarily mounted tapes before)
However, I do have this line in sd conf:
AutomaticMount = yes;
Any ideas what is causing this / how to make things run more smoothly?
This is unfortunately slow to debug, since the problem appears about once in
a month...
