I've tested mt with both the by-id and with /dev/nst0, and it works
identically. Similarly, mtx-changer works perfectly with both the by-id and
the /dev/autochanger1 names. I haven't tested the naked mtx command, but since
mtx-changer uses mtx, I figure that would be a valid test.
btest works perfectly with both the by-id name and with /dev/nst0
Unfortunately, bacula also works identically with both the by-id name and with
/dev/nst0, and not in a good way. I have altered my configuration to be
identical with what you have suggested below, and it fails in exactly the same
manner as before.
Since the by-id names are themselves symlinks to the same special files that I
was using before, unless I change the hardware, I can't imagine any churn in
those devices. There will only ever be one /dev/nst0, since there will never
be another tape drive added, and /dev/autochanger1 will always point to the
correct changer device since it's set by udev based on the specifics of this
changer. Using the by-id name isn't a bad idea, but I don't think it's related
to this problem.
Is there maybe some way to generate a debug log that has more information than
what shows up in the director? "3999 Device "AutochangerOdin" not found or
could not be opened" isn't very clear.
Could this be a permissions issue? Both raw devices (/dev/sg3 and /dev/nst0)
are owned by the "tape" group, and I double checked that the storage daemon
*is* running as group "tape."
I'm still at a loss here.
