Boa tarde Pessoal,

Estou com um servidor de backup bacula funcionando corretamente até o momento que precisei utilzar o backup em FITA LTO-4.

Meu sistema esta virtualizado em um VMware ESXi 5.5 e com Sistema Operacional CentOS 6 e Bacula 5.0.

O Backup local em diretório e feito normalmente porém quanto tento utilizar a Fita LTO-4 o dispositivo não é reconhecido, se eu utilizo o utilitário do btape do próprio bacula eu consigo manipular a Fita normalmente, segue abaixo a saida do mesmo.

Alguém tem alguma ideia do que possa ser ?

OBS: os testes de dos arquivos de configuração não apresentam nenhuma saída de erro.

*test

=== Write, rewind, and re-read test ===

I'm going to write 10000 records and an EOF
then write 10000 records and an EOF, then rewind,
and re-read the data to verify that it is correct.

This is an *essential* feature ...

btape: btape.c:1148 Wrote 10000 blocks of 64412 bytes.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:1164 Wrote 10000 blocks of 64412 bytes.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:1206 Rewind OK.
10000 blocks re-read correctly.
Got EOF on tape.
10000 blocks re-read correctly.
=== Test Succeeded. End Write, rewind, and re-read test ===

btape: btape.c:1274 Block position test
btape: btape.c:1286 Rewind OK.
Reposition to file:block 0:4
Block 5 re-read correctly.
Reposition to file:block 0:200
Block 201 re-read correctly.
Reposition to file:block 0:9999
Block 10000 re-read correctly.
Reposition to file:block 1:0
Block 10001 re-read correctly.
Reposition to file:block 1:600
Block 10601 re-read correctly.
Reposition to file:block 1:9999
Block 20000 re-read correctly.
=== Test Succeeded. End Write, rewind, and re-read test ===



=== 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:578 Rewound "LTO-4" (/dev/st0)
btape: btape.c:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:476 open device "LTO-4" (/dev/st0): OK
btape: btape.c:578 Rewound "LTO-4" (/dev/st0)
btape: btape.c:1418 Now moving to end of medium.
btape: btape.c:629 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:1905 Wrote one record of 64412 bytes.
btape: btape.c:1907 Wrote block to device.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:578 Rewound "LTO-4" (/dev/st0)
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:578 Rewound "LTO-4" (/dev/st0)
btape: btape.c:813 Wrote first record of 64412 bytes.
btape: btape.c:824 Wrote second record of 64412 bytes.
btape: btape.c:835 Wrote third record of 64412 bytes.
btape: btape.c:608 Wrote 1 EOF to "LTO-4" (/dev/st0)
btape: btape.c:851 Backspaced over EOF OK.
btape: btape.c:856 Backspace record OK.
btape: btape.c:874
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
