I think you're right that Bacula tracks this itself too, but
"mtx-changer /dev/ch0 loaded" is written to report the slot number
that's loaded into the drive itself. This is also how Bacula
interprets it. Anyway, I'll save my changes to this script until I've
finished testing them.
On another note, I've discovered that I jumped the gun when concluding
that the sd hung without a tape. btape does indeed eat itself when the
there's no tape, but the sd was apparently just waiting for the
"Maximum Open Wait" window to expire before it would respond to status
requests. After five minutes of this:
----
*status storage
Automatically selected Storage: Tape
Connecting to Storage daemon Tape at 10.123.0.17:9103
----
I finally got a reply. Decreasing this window to 30 seconds makes it a
bit more palatable, though I have to test to make sure this isn't
going to cause other problems.
Thanks for the help, and sorry for misunderstanding that behavior.
