Hi,
I'm trying to get a Quantum DLT-V4 SATA to work on my Debian Etch Bacula
setup. My knowledge about Linux is good, but I don't have a lot of
experience with Tape drives and/ or Bacula. Did a lot of testing with
btape (as in days), but it is still not working. I'm really done with
testing, therefore my hope is targeted at some gurus on the mailinglist
that can tell me what is wrong (or what I am doing wrong).
Any help would be great!
Some notes:
If I schedule a backup inside Bacula it works (completes successfully).
I can't do a restore, which gives me the same errors as with btape.

When i do a btape test, everything seems ok:
-------------------------------
=== Write, rewind, and re-read test ===
I'm going to write 1000 records and an EOF
then write 1000 records and an EOF, then rewind,
and re-read the data to verify that it is correct.

=== Test Succeeded. End Write, rewind, and re-read test ===
=== Write, rewind, and position test ===
I'm going to write 1000 records and an EOF
then write 1000 records and an EOF, then rewind,
and position to a few blocks and verify that it is correct.

and three records in file 2

btape: btape.c:490 Moved to end of medium.
We should be in file 3. I am at file 3. This is correct!
Now the important part, I am going to attempt to append to the tape.
btape: btape.c:1531 Wrote one record of 64412 bytes.
btape: btape.c:1533 Wrote block to device.
btape: btape.c:469 Wrote 1 EOF to "DLT-V4" (/dev/nst0)
btape: btape.c:438 Rewound "DLT-V4" (/dev/nst0)
Done appending, there should be no I/O errors
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.
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 ...
btape: btape.c:438 Rewound "DLT-V4" (/dev/nst0)
btape: btape.c:674 Wrote first record of 64412 bytes.
btape: btape.c:685 Wrote second record of 64412 bytes.
btape: btape.c:696 Wrote third record of 64412 bytes.
btape: btape.c:469 Wrote 1 EOF to "DLT-V4" (/dev/nst0)
btape: btape.c:712 Backspaced over EOF OK.
btape: btape.c:717 Backspace record OK.
btape: btape.c:735
Block re-read correct. Test succeeded!
=== End Write, backup, and re-read test ===
=== Forward space files test ===
This test is essential to Bacula.
I'm going to write five files then test forward spacing

I tried appending "irqpoll acpi=noirq" to see wether it is a kernel
problem, but that didn't make any difference. As writing seems to work,
I guess it is not a kernel problem.
