running bacula 2.0.3 with mysql 4.1.13 on SuSE 10.0;
mtx 1.3.10; smartctl 5.36
ADIC scalar-100 with 4 LTO-1 drives

Hello,

I had some strange problems with bacula.
Main effect:
I am running 3 concurrent jobs every day which use 3 drives. Because of
the "suboptimal" method of picking a drive for a job (as recently
reported) bacula keeps changing the drives for the jobs so it has to
unload / load the tapes.
Somtimes the tapes could not be appended to after they where moved from
one drive to another.

After several days of testing and searching (in fact using 3 different
scsi-controlers) i finally got the culprit.

It was the "Alert Command = " line calling tapeinfo which seems to reset
the scsi controller. So the first job which finishes called tapeinfo
which reseted the scsi-bus and so confusing the still running jobs on
the other drives.

After disabling the Alert Command i got no more reset messages in the
message-log and no more problems with the tapes.

As far as i can tell by now (just tested once) the problem does not
concern smartctl.


Andreas
