Hello !
I have bacula Version: 5.2.1.
I want to backup datas on a autoloader quantum i80 with 2 drives.
What OS are you using? That can affect the configuration.

The bacula test works correctly:
root@backup1:~# btape -c bacula-sd.conf /dev/nst0 .
btape: btape.c:476 open device "Drive-i80-1" (/dev/nst0): OK
*test
...
We should be in file 5. I am at file 5. This is correct!
Do you wish to continue with the Autochanger test? (y/n): y
=== Autochanger test ===
The test autochanger worked!!
But when I run a job I have this mess :
15-Nov 23:33 backup1-sd JobId 3: Writing spooled data to Volume. Despooling 107,374,192,579 bytes …
I do this test :
root@backup1:~# btape -c bacula-sd.conf /dev/nst0
Tape block granularity is 1024 bytes.
btape: butil.c:290 Using device: "/dev/nst0" for writing.

result is Slot 1.
btape: btape.c:476 open device "Drive-i80-1" (/dev/nst0): OK
*fill
This command simulates Bacula writing to a tape.
It requires either one or two blank tapes, which it
will label and write.
If you have an autochanger configured, it will use
the tapes that are in slots 1 and 2, otherwise, you will
be prompted to insert the tapes when necessary.
It will print a status approximately
every 322 MB, and write an EOF every 1.000 G. If you have
selected the simple test option, after writing the first tape
it will rewind it and re-read the last block written.
If you have selected the multiple tape test, when the first tape
fills, it will ask for a second, and after writing a few more
blocks, it will stop. Then it will begin re-reading the
two tapes.
This may take a long time -- hours! ...
Do you want to run the simplified test (s) with one tape
or the complete multiple tape (m) test: (s/m) m
Multiple tape test selected.
Wrote Volume label for volume "TestVolume1".
Wrote Start of Session label.

The tape media status is Full.
What do you think about this option :
Hardware End of Medium = no ??
Do small local jobs work? When setting up a new install, I
prefer to start small and increase job size later.
By small local, I mean back up the machine upon which the
SD is located. To keep things simple, do not use spooling for
that job.*
It works.

There's lots in Google about this error, but I stopped
looking when I didn't locate a suggestion right away.
There were suggestions to activate a sleep in the
mtx-changer file. However, it seems that writing has already
occurred by the time this error has occurred. The sleep
command is usually added to let the tape mount full complete
before writing starts.
I try this parameter :
Maximum Changer Wait = 6000

Usually, these errors indicate a network problem…. but
with the error above, I think not.
Datas are transfered from spooldata to i80.

After you get writes working, consider using different

is a good suggestion.
