Hi Michael. I've been modified the mtx-changer script, increasing the
sleep time in the load case section since I got the following error
mentioned in a previous message of this thread:
3912 Failed to label Volume: ERR=dev.c:678 Rewind error on "Drive-1"
(/dev/nst0). ERR=Error de entrada/salida.
------------------------------------------------------
load)
debug "Doing mtx -f $ctl load $slot $drive"
${MTX} -f $ctl load $slot $drive
rtn=$?
#
# Increase the sleep time if you have a slow device
# or remove the sleep and add the following:
# wait_for_drive $device
# sleep 15
sleep 60
exit $rtn
;;
------------------------------------------------------
Reading the "Autochanger Resource" section of Bacula's manual,
subsection "Testing Autochanger and Adapting mtx-changer script", I
found this:
If Bacula complains "Rewind error on /dev/nst0. ERR=Input/output error."
you most likely need more sleep time in your mtx-changer before
returning to Bacula after a load command has been completed.
Then, I ran a new test using btape:
------------------------------------------------------

Doing Bacula scan of blocks:

End of File mark.

End of File mark.

End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 4. This is correct!
The above Bacula scan should have output identical to what follows.
Please double check it ...
=== Sample correct output ===
1 block of 64448 bytes in file 1
End of File mark.
2 blocks of 64448 bytes in file 2
End of File mark.
3 blocks of 64448 bytes in file 3
End of File mark.
1 block of 64448 bytes in file 4
End of File mark.
Total files=4, blocks=7, bytes = 451,136
=== End sample correct output ===
If the above scan output is not identical to the
sample output, you MUST correct the problem
or Bacula will not be able to write multiple Jobs to
the tape.
=== Write, backup, and re-read test ===
I'm going to write three records and an EOF
then backup over the EOF and re-read the last record.
Bacula does this after writing the last block on the
tape to verify that the block was written correctly.
This is not an *essential* feature ...

Ah, I see you have an autochanger configured.
To test the autochanger you must have a blank tape
that I can write on in Slot 1.
Do you wish to continue with the Autochanger test? (y/n): y

Slot 4 loaded. I am going to unload it.
3302 Issuing autochanger "unload 4 0" command.

The test autochanger worked!!
------------------------------------------------------
All the tests seems finished successfully!!
Well, it's a good step in the correct direction :-)
Now I'm trying to perform backups operations. I've noticed when I try
label a volume, Bacula uses the slot 0 and then it causes a mount error.
------------------------------------------------------

------------------------------------------------------
I have seen some cases where Bacula asks on the slot for the volume. How
I can obtain this behavior?
Thanks for your response.

Daniel
