Hello,
I'm having a strange problem. I have a bacula setup with a tape
library and 3 drives. Backups on one of the drives are not working. No
error message, the jobs just queue up and then don't run. They don't
seem to select a volume. The problem is with my tape labelled LTO-5-1.
Here is the status output:

Another strange thing is that despite what the status says, there are
volumes loaded (from mtx):
Storage Changer /dev/changer:3 Drives, 47 Slots ( 3 Import/Export )
Data Transfer Element 0:Full (Storage Element 11 Loaded):VolumeTag =
000011L5
Data Transfer Element 1:Full (Storage Element 24 Loaded):VolumeTag =
000027L6
Data Transfer Element 2:Empty
0 is LTO5-1, 1 is LTO-6-1 and 2 is LTO-6-2.
I ran a test with btape and it's able to write to LTO5-1, so I'm
guessing that the issue is pool related?
