./bconsole
mount
1
will mount the tape loaded in /dev/tape1 , but I guess you will get the same
problem as I have, where bacula select Drive-0 but will use the tape mounted in
Drive-1 , and the result will be that bacula unload drive-0 and send load x 0 to
the exchanger, that can't load the tape since it's loaded already.
This part must be rewritten I think :-(
It was working fine for me when I had a pool for each drive, but when I changed
to only one storage device (the autochanger) , I can't bind a drive to a pool
any more, nor limit the jobs/tape.
If you set "Prefer Mounted Volumes = no" on each Job{} , it will work good
enough, but it can still happen that bacula will mount a tape that is loaded in
an other drive.
