Re: [Bacula-users] job canceled - block.c:318 Volume data error at 0:0!

Hello,

2013/7/23 Markus Rosjat <rosjat AT ghweb DOT de>

HEy there,

I have a problem with a scheduled job that I run, the requested Tape
is in the loader and gets mounted but I get a Volume Data Error and
Bacula tells me to mount the Tape or label a new one. Im pretty lost
with that behaviour, I canceled the job and checked what status the tape
has (its recycle) the retention time is 25 days and the last use was
2013-05-30. I purged the tape und mounted the tape manually and try to
run the job but it still refuse to run.

here is a log of the last scheduled job that I had to cancel again so
other jobs can run:

This a main problem. Your volume is corrupted.

In my opinion you should erase (with deleting it from catalog) a tape and label it again. If problem will still exist dispose a tape and get a new one.

best regards
