I'm getting a little frustrated trying to bring my new backup server online.
I'm running Debian Stretch on a Dell R730, hooked to a Dell TL200 library over
SAS. The library has a single LTO6 drive. Bacula 7.4.4 is installed, and as
far as I can tell is correctly set up and configured. It passes all the btape
diagnostics with no trouble. However, nothing I try from inside bacula itself
seems able to access the tape drive itself. It *is* successful in manipulating
the robotics however:
*mount storage=Library2 slot=1 drive=0
3304 Issuing autochanger "load slot 1, drive 0" command for vol .
3305 Autochanger "load slot 1, drive 0", status is OK for vol .
3001 Mounted Volume: 000015L6
3001 Device ""Drive-1" (/dev/nst0)" is already mounted with Volume "000015L6"
This is my second bacula installation. My previous backup server (currently
running on Debian Jessie) has been successfully backing up half a dozen clients
for ten years on a different TL2000 using LTO3 tapes.
It started with an inability to label the tapes. Then I noticed that btape
allows you to do a label, so I went through and labeled each cartridge by hand
in btape, recognizing that I'd have to add them to the catalog by hand, hoping
that the problem was just with the label command. OK, wishful thinking...
All my volumes are now labeled and in the catalog:

the system to go the the hardware, which is a hint that it's probably a

What the error message seems to be telling me is that there is no device
"AutochangerOdin" defined in the storage daemon. The following is the stanza
for the autochanger in bacula-dir.conf:
#From bacula-dir.conf
# Definition of tape library device
Storage {

# Do not use "localhost" here
Address = odin # N.B. Use a fully qualified name here
SDPort = 9103
Password = "mypassword"
Device = AutochangerOdin
Media Type = LTO6
Autochanger = yes # enable for autochanger device
}
Here is the section in bacula-sd.conf:
#From bacula-sd.conf

# ONE drive!
Autochanger {

}

# # not seem to cause such problems.
# #
#Alert Command = "sh -c 'tapeinfo -f %c |grep TapeAlert|cat'"
# If you have smartctl, enable this, it has more info than tapeinfo
Alert Command = "sh -c 'smartctl -H -l error %c'"
}
My previous run at this (last fall) I got the advice to use by-id or by-path
devices, but that is irrelevent, because those are just symlinks to the real
devices, so I went back to the real devices. It might make a difference if I
was rebooting the system regularly and if I didn't have udev rules in place to
keep the devices constant, but it's not a factor here.
What I'm hoping for is that there *is* a misconfiguration that I'm just not
seeing. When I look at it, it seems fine to me, but I'm hoping someone else
can see what's not obvious to me. Why would the director think the device
"AutochangerOdin" does not exist? Or is that a red herring? Is it a problem
with the definition of the Media Type? The catalog shows a MediaType of LTO6,
but the error message from the failed backup shows a lot of parameters, but no
MediaType. Could this be related? How would I fix that?
Thanks for any advice.
