Bacula is designed to decide itself which tapes to use and when. If you are trying to force it to use particular tapes it is possible, but it is outside the design envelop, so you will almost surely run into problems.

Just encountered the situation again.
Bacula requested last month's tape "Januar" since its use period hadn't
expired yet, but it's the next full backup which should go onto the new
month's tape "Februar".
Tape "Januar" has VolStatus=Append.
Tape "Februar" has VolStatus=Used with VolFiles=0 since it's way beyond
any applicable retention periods, but Bacula rejects it because of its
Status and never considers promoting it to "Purged" .

Running bconsole command "prune volume=Februar" asks for confirmation,
then emits the message

   Found no Job associated with the Volume "Februar" to prune

and does nothing. Bacula continues to reject the tape.

Running bconsole command "purge volume=Februar" emits an alarming message

   This command can be DANGEROUS!!!

then proceeds, *without* waiting for confirmation, to update VolStatus
of tape "Februar" to Purged. Now Bacula accepts the tape.

Is all that how it should be?

Is there a way to run the purge command automatically for volumes that
have reached the "VolStatus=Used && VolFiles=0" state?

Thanks,
Tilman

running Bacula 7.4.4 (same problem with version 5.2.13) on openSUSE Leap

[Sometimes Bacula requests] a tape that for some
reason cannot or should not be used for that job.
Then if I mount a different tape, Bacula will immediately eject it
again, claiming that it is in the wrong state ("Used" instead of
"Recycle") and insisting I mount the one it requested.
How can I convince Bacula to recycle and use the tape I give it?
You can forccefully recycle this tape with the purge command.
Ok, that worked, but I'm not quite happy with that solution yet.

* The situation has occurred again today, Bacula requesting volume
"Mai-2" instead of "Januar" which I wanted it to use.
* I first checked volume "Januar" which had not been in use for way
beyond its retention period of 91 days, and was listed in the catalog
with VolFiles=0, so it should be available for recycling:

* I tried to prune the volume. Bacula asked me whether I was sure, then
told me there was nothing to do:

*prune volume=Januar
The current Volume retention period is: 3 months 1 day
Continue? (yes/mod/no): yes
Found no Job associated with the Volume "Januar" to prune

After that, Bacula would still eject the volume, asking I insert volume
"Mai-2" instead.

* Only when I actually purged the volume Bacula marked it as purged and
subsequently accepted to use it:

*purge volume=Januar

This command can be DANGEROUS!!!

It purges (deletes) all Files from a Job,
JobId, Client or Volume; or it purges (deletes)
all Jobs from a Client or Volume without regard
to retention periods. Normally you should use the
PRUNE command, which respects retention periods.
There are no more Jobs associated with Volume "Januar". Marking it purged.

Isn't that the wrong way around?
Shouldn't Bacula ask for confirmation on the *dangerous* command, and
execute the *safe* one without asking?
And shouldn't there be a non-dangerous way to promote a volume that
*already* has no more jobs associated with it from status Used to Purged?

Thanks,
Tilman
