Hi Koshi
I seem to have a similar problem (in bacula 3.0.3). After purging the volume,
it indeed has no more associated jobs as may be verified in the JobMedia table
(select * from JobMedia where MediaId = ID). However, the volume is not emptied
and upon reuse it seems to be full already. Previously, manual purging this way
always worked fine for me.
The only hypothesis i have as to why this could occur is that due to growing
job sizes the data that remains originates from a job that was started on
another tape (and completed on this one). But i am not sure about this at all,
and have no solution path at the moment. Anyone has a solution for this issue
or a hint to diagnose it further?
Best
Thomas
