OK, so it looks like the data on the tape is still OK.
The Volume=0 in the error message is what Bacula found for the "file" position
on the tape after trying to move it to the end of data. This might be a bug
in the OS driver or tape firmware. Were there any syslog messages at that
time?
You could try running btape and issuing the commands
rewind
cap
eod
status
to see what it reports. (I don't think this will write anything to the tape.)
Also, have you run the btape test command successfully with this configuration
recently? (Beware that this will overwrite the tape.)
