Hi folks,
Just as I thought I have fixed my problems, I am again stumped with Volumes
being put into Error with "*Error: Unable to position to end of data on
device*" messages.
As previously mentioned in my other post, all the tapes were erased once
over to make sure everything starts cleanly. The tapes were bought brand new
from IBM and some were used previously for my Bacula tests (btape + actual
backups).
analysing the pattern, I suspect once all the backups are done EOF/EOD is
not written to the tape/volume causing next run(s) to put the tape into
Error and use the next available volume.
Following is part of the output from btape tests I did earlier.
Doing Bacula scan of blocks:
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.
*17-Oct 09:43 btape JobId 0: Error: block.c:995 Read error on fd=3 at
file:blk 4:0 on device "LTO4_1" (/dev/IBMtape0). ERR=Input/output error.*
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!
Following is the excerpt of last night's backups.

Is there a certain parameter I need to set for the LTO4 tape drive to write
EOF/EOD after the backups are done?
Help is much appreciated.
