[Bacula-users] bacula-sd hangs after tape error

Hi,

I am using bacula 2.2.8, SuSE linux 10.1 and a Benchmark DLT1 tape drive. Today, a backup which spans multiple tapes failed because of a tape error. I could not unmount the tape, and bacula-sd told to the director: "Device /dev/nst0 is busy in acquire." Which obviously was wrong, because the tape did nothing any more. I gave up the hope that I could proceed the backup with a new tape now, stopping bacula in order to get rid of the stuck bacula-sd process. Now, bacula-sd is a zombie process and still occupies the tape device.

I think this is a bug. When a tape error occurs (which is quite normal because tape are mechanical parts and those errors should be handled by software), bacula-sd should unmount the tape and wait for a new appendable tape to be mounted. Bacula should then rewind the backup to the position before the failed tape, so the operator can throw the failed tape away and replace it by a better one without losing data.

Greetings,

Tobias Barth
