I got around the problem by starting the bacula-sd process as root.

Hi,
I don't recall if this was discussed on the mailing list any further -
which I'd suggest - but if this is not a simple permissions problem it
might be time to take a really close look at what mtx-changer does, and
why it doesn't recognize the number of slots.
Simply check what it does with mtx, and see what mtx outputs in such a
situation.

I have a problem and I need your help.
Last week I upgraded our quantum superloader to a superloader 3. For
the first few days everything worked well. But since this weekend,
bacula can't seem to properly control the autoloader. Here's the
error I get when I try to update the AutoLoader's slots:
Connecting to Storage daemon AutoLoader at bacula:9103 ...
3306 Issuing autochanger "slots" command.
Device "AutoLoader" has 0 slots.
Ah. Permssions probably.
I suppose that your autoloader has a new device node now which can't
be accessed by the SD. Assuming the SD is not running as root, ...
No slots in changer to scan.
Yet I can do this command: ./mtx-changer /dev/sg3 slots AutoLoader 0
and get 16 as the number of slots. This is what I get after doing
this command: ./mtx-changer /dev/sg3 list AutoLoader 0

... but you are logged in as root.
What happens when you log in as the Bacula user and issue
'mtx-changer /dev/sg3 slots'?
I did it as the user bacula and root, and got the same result for both.
ls -la gives
crw-rw---- 1 root disk 21, 1 Nov 20 07:02 /dev/sg1
and
id bacula gives
uid=100(bacula) gid=6(disk) groups=6(disk),102(bacula)
Something else is causing my permissions problem.

So at first, it looks like the mtx-changer properly gets the output
but not bacula through the bconsole shell.
I also get these errors in my log when the unit is trying to perform
backups:
19-Nov 21:11 bacula-sd: 3301 Issuing autochanger "loaded drive 0"
command.
19-Nov 21:11 bacula-sd: 3991 Bad autochanger "loaded drive 0"
command: ERR=Permission denied.

What's going on? How can I fix this?
