Arno,
What happens when mount is issued: it came back with the "waiting on
Storage" error. I cannot show this to you now as I have had to try other
things. The drive itself has been replaced with one that has Quantum's
latest and greatest firmware - guess what - same result. So I am looking
at the Volume max jobs because of the message 'Volume max jobs
exceeded.' It seems bacula is looking first at that Max Jobs value
before proceeding to recycle the tape (even though the catalog was
marked for the tape/volume to be recycled) The example I presented in
this thread included three full backup jobs on Friday, three
differential on Saturday, and three on Sunday, a total of 9 jobs. Two of
the jobs are typical, the third is the catalog backup. It doesn't matter
whether it's the Friday tape, or the Monday or Tuesday etc. I always ran
this situation [with my Quantum 40/80 and no problems] with Max Vol Jobs
= 9 on Friday (really Friday thru Sunday 1 tape), and Max Vol Jobs = 3
Monday thru Thursday (4 tapes). When I set it to 2, the tape recycles
properly, but then I'm left waiting to mount a new tape for the third
job. The only reason for the Max Vol Jobs was to get the tape to become
Used. So now I am trying no value for Max Vol Jobs, and setting Volume
Use Duration for 23h to see if this solves what I believe is still
basically a hardware <-> bacula issue.
These Quantum 160/320 SDLT are known to be tricky and finicky as
compared to the 40/80 DLT, unfortunately, but I have to find a way to
live with them as I have 4 of them!
I'll report on my success or failure - I appreciate any and all support.
It is sometimes hard to describe concisely just what is going on...
