I think so. I thought that this was supposed to be fixed though.

I am having this same issue.  Up until now, it had been intermittent.
Today, I am consistently having the issue.  I have 6 tape drives in my
changer.  I have 4 jobs running, each using a separate tape/drive all in
the same pool.  I've been manually starting another job which selects one
of the free tape drives, but is asking for a tape that is currently in use
in drive-0.  I have canceled and restarted the job several times, started
a different job (it asks for the tape in drive-0), manually mounted an
available tape into drive-1, all of which has only resulted in the tape
being unmounted from drive-1 and the tape in use in drive-0 being
requested. I think it can be said that this is not a race condition.

Addendum: I used an unmount command to BLOCK the drive.  This seems to
have broken the hold as the job selected the remaining open drive to use
and the tape that I'd mounted there.

Re: [Bacula-users] bacula confused about volumes

2012-08-05 Thread Stephen Thompson 


We're seeing this with a lot more frequency, though we've changed no 
configuration.  Jobs are often left waiting an entire run in order to 
use a volume that's in use by the other drive within a 2 drive changer.

 Hey all,

 I've been meaning to post about this for awhile, but it comes up pretty
 rarely (maybe once every few months running hundreds of job a night).

 With an autochanger with 2 drives, each set to AutoSelect, it's possible
 for bacula to want the same volume in both drives at the same time,
 which creates an Operator Intervention situation.

 Here's an example where apparently previous jobs were using a particular
 volume in one drive and somehow jobs assigned to the other drives wanted
 the exact same volume, causing them to pause and require operator
 intervention.
