Hmm. I don't remember if you told us which version of Bacula you're running.
I'm running 1.38.5 upgraded from 1.38 (which is the earliest version
I've used)
Your problem sounds like you either use 1.36, or have recently upgraded
and didn't "clean up" the catalog.
Nope, thats not it.
In case you use 1.36, I'd recommend to upgrade to 1.38.5 as long as
you're still setting everyting up. If you want or have to continue with
1.36, you need to separate your volumes into two pools, each of which
should only be used in one autochanger.
So it should be OK to mix tapes from different pools in a given
autochanger in 1.38.5?
It should, or rather, I can't remember anything from the ReleaseNotes
and the development list that it shouldn't be possible. *If* 8really big
If...) I find the time I might look into the source code and try if I
can track down how volume selection takes place. That might take some
days, though.
If you're already using 1.38, you should check if the volumes are
correctly assigned to the storage device the're in - either use the
llist command, or use the query that tells you which media is in which
autochanger and which slot (that one was added to the default query.sql
file recently, but you might find it in the list archives, too).
OK, I did that and it looks right:
Choose a query (1-17): 16

One guess at what's happening is that the job is looking for the oldest
appendable tape which is in a changer and decides that's the one it
wants to use and gets its slot number. The problem is that the tape is
in the 2nd changer, not the one the job is using. So it seems as if the
job has the drive that it's using switch to the slot number
corresponding to the tape in the other drive and then realizes that it
can't use the tape that it finds there.
Well that's my current theory anyway. Please let me know if you have
anymore insights.
Nothing, currently.
The work-around seems obvious, though: Create more pools, and use tapes
from one pool in one autochanger only. Or use different media types.
Both can easily be reverted when Bacula correctly supports your setup
;-) And to get there earlier, you should file a bug report a
bugs.bacula.org - I think you've got all the necessary information to
make that one a really well documented bug. If nothing else, a bug
report forces Kern to decide if it's abug or not ;-)
