Hi Kern, et al,

I've noticed a pattern in my backups when two jobs are simultaneously writing to the same tape. When the tape ends, Bacula doesn't respond gracefully. This is only a problem when two jobs are running on the
tape, not when a single job is running.

Are you spooling to disk or writing directly to tape?

I'm writing directly to tape. Do you suppose that this may be remedied by
spooling? My initial tests with spooling showed a performance hit

It's clear you've tickled a bug and I hope you've filed it on
bugs.bacula.org.

I think it is more likely that the user did not properly test with btape test.

Yeah, it might appear that way :)
But I did perform the btape tests, and everything checked out OK.


I cannot completely exclude a bug, but I find it unlikely. I'd like clear
evidence of a bug, which I don't have, before spending any time on the
problem.

Maybe it's not a bug in bacula. This is why I haven't filed one yet. Perhaps it's a problem with my setup. I'm just looking for ideas, and I find it curious that one-at-a-time jobs work as expected, while simultaneous jobs will produce these errors more often than not.

Best,
Ian
