Hello group,
Lately I have a rather annoying problem. I'm using bacula already for
quite a long time with my AIT4 Changer without problems. I don't know
exactly since when (maybe during upgrades), but lately backups are often
failing and I don't know why. Bacula asks to mount a volume, for example :
06-Dec 03:21 bacula-sd JobId 16918: Please mount Volume "A082Y2" or label
a new
one for:
Job: OblTape.2008-12-05_21.00.29
Storage: "AIT4-1" (/dev/nst0)
Pool: FridayPool-Tape
Media type: AIT4
However, update slots has been run before, the volume is in the changer,
but it seems like Bacula doesn't run the mtx-changer script for one
reason or so.
The problem is that this behaviour is not consequent. Sometimes the backup
just works. When it doesn't work (and asks for a tape), then I try to type
'mount', but then I just get the message 'OK Mount' but nothing happens.
The same with umount.
I've tried running btape with the 'test' and the 'fill' command (complete
test with 2 tapes) again, which works without problems and happily changes
tapes.
Currently I'm using Bacula 2.4.3 with all the latest patches (incl.
slots-patch).
This is my relevant bacula-sd.conf information for the autochanger:
Autochanger {
Name = Autochanger
Device = AIT4-1
Changer Command = "/usr/local/bacula/etc/mtx-changer %c %o %S %a %d"
Changer Device = /dev/sg0
}
Device {
Name = AIT4-1
Drive Index = 0
Media Type = AIT4
Archive Device = /dev/nst0
AutomaticMount = yes; # when device opened, read it
AlwaysOpen = no;
RemovableMedia = yes;
RandomAccess = no;
AutoChanger = yes;
Alert Command = "sh -c 'tapeinfo -f /dev/sg0 |grep TapeAlert|cat'"
Spool Directory = "/mnt/storage/spool"
}
I don't see any errors in the working log.
If anybody has an idea how I can try to find out further where the problem
lies, or what I can do to debug things furher, please let me know.
Thanks!
K.
