Hi,
I have come across some strange behaviour of bacula today and I would
like to know if someone else has encountered this one.
About my scenario:
I use a SATA-Backplane with 4 harddiscs for backup. bacula is configured
to accept this as an autochanger wiht 4 slots and starts an
autochanger-script which mounts and unmounts the correct volume. This
works pretty fine.
Today I was about to change the discs again and wanted to use the
opportunity to give this system the ability to read the labels and
update the labels from the script.
I adapted my script according to the manual to produce the right output
for the command "list". So far so good.
When I try to run the command "update slots (scan)" in the console it
fails. bacula complains that the device is not an auto changer.
"3995 Device /mnt/backup-disc is not an autochanger."
This is a fact, but all the time bacula accepts this device as an
autochanger, when I start backups. It rotates the discs, mount them
properly and so on.
Is there a difference in the treatment of this device between backing up
an scanning, which could explain this?
The used bacula version is bacula-postgresql-1.36.2-1.
I have added excerpts of the used config-files.
Best regards
Daniel Blömer
