Re: [Bacula-users] question reguarding autochanger use

I think I recently saw this problem too. The problem as I saw it was
when I did added new unlabeled tapes to my changer. My changer Dell
PowerVault 136T managed to accept tapes that it shouldn't. I have two
drives and both had tapes in them. When it imported the tapes from the
in/out slots to the regular slots it put them in slots which should have
been reserved (due to the tape not being in it's regular slot but being
loaded in a drive). As a result, when bacula went to unload a drive the
home slot was full and couldn't be used. Unfortunately, when I ran an
update slots on the changer it became apparent that somewhere in the
code for either the director or sd bacula wasn't updating the slot info
for mounted tapes.
I had to use the right mtx command to unload the tape and then restart
bacula to get that resolved I think.
Is it possible you were having new tapes imported while drives were full
too?
