I continue to be plagued with the problem shown below. About 80% of the time
it
works perfectly. The rest of the time I have to use bconsole to unmount, then
mount
the tape again. The second read always works and the backup continues. Of
course it
happens in the middle of the night when the changer switches tapes and so I
have to
intervene the next day.
The good news is this has nothing to do with the tape change. The mtx-changer
script
is waiting until the mt command returns a status of ONLINE. It does so
successfully,
and I can see it in the mtx-changer log. This means the drive was able to read
the
system area of the tape and is happy with it. I don't know why then bacula has
trouble reading the data portion.
I'm thinking about writing a script that cron could run every hour to see if
the
device is blocked even if the correct tape is loaded. If so, it could do a
unmount/mount. Or maybe I could add some command to the changer script to read
some
data off the tape after it loads or something? Or maybe bacula could be
improved to
try harder (whatever that means) to resolve the issue on its own?
Bacula 2.2.8 with a VXA320 drive and packetloader changer.
Thanks for any ideas.
