[Bacula-users] Solaris error positioning end of data

Hi all

found a problem to write multiple jobs on a tape. When run first job on 
a new labeled tape, it finish ok. But when i try to run another job on 
this tape, appears this error:

* Volume "Diario-01" previously written, moving to end of data.
* Error: Unable to position to end of data on device "HP-Drive" 
(/dev/rmt/0cbn): ERR=dev.c:1326 read error on "HP-Drive" 
(/dev:/rmt/0cbn). ERR=Error de E/S.

Btape test appears to be 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.

This is an *essential* feature ...

=== 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.

This is an *essential* feature ...

=== Append files test ===

This test is essential to Bacula.

I'm going to write one record  in file 0,
                   two records in file 1,
             and three records in file 2

btape: btape.c:475 Rewound "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:1577 Wrote one record of 64412 bytes.

btape: btape.c:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:372 open device "HP-Drive" (/dev/rmt/0cbn): OK
btape: btape.c:475 Rewound "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:1097 Now moving to end of medium.
btape: btape.c:526 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:1577 Wrote one record of 64412 bytes.
btape: btape.c:1579 Wrote block to device.
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:475 Rewound "HP-Drive" (/dev/rmt/0cbn)
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:475 Rewound "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:710 Wrote first record of 64412 bytes.
btape: btape.c:721 Wrote second record of 64412 bytes.
btape: btape.c:732 Wrote third record of 64412 bytes.
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:505 Wrote 1 EOF to "HP-Drive" (/dev/rmt/0cbn)
btape: btape.c:748 Backspaced over EOF OK.
btape: btape.c:753 Backspace record OK.
btape: btape.c:771
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

Any idea?
