Hi,
I've made a new test-run wirh btape.
btape means all running fine (output below)....
What can I check or do to clarify the Problem? Any Ideas?
btape Output:
Tape block granularity is 1024 bytes.
btape: butil.c:292-0 Using device: "HP-Ultrium3000" for writing.
btape: btape.c:499-0 open device "HP-Ultrium3000" (/dev/nst0): OK
*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:1184-0 Wrote 10000 blocks of 64412 bytes.
btape: btape.c:631-0 Wrote 1 EOF to "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:1200-0 Wrote 10000 blocks of 64412 bytes.
btape: btape.c:631-0 Wrote 1 EOF to "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:1242-0 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:1310-0 Block position test
btape: btape.c:1322-0 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 Bareos.
I'm going to write one record in file 0,
two records in file 1,
and three records in file 2
btape: btape.c:601-0 Rewound "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:1941-0 Wrote one record of 64412 bytes.
btape: btape.c:1943-0 Wrote block to device.
btape: btape.c:631-0 Wrote 1 EOF to "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:1941-0 Wrote one record of 64412 bytes.
btape: btape.c:1943-0 Wrote block to device.
btape: btape.c:1941-0 Wrote one record of 64412 bytes.

btape: btape.c:1943-0 Wrote block to device.
btape: btape.c:631-0 Wrote 1 EOF to "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:499-0 open device "HP-Ultrium3000" (/dev/nst0): OK
btape: btape.c:601-0 Rewound "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:1454-0 Now moving to end of medium.
btape: btape.c:652-0 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:1941-0 Wrote one record of 64412 bytes.
btape: btape.c:1943-0 Wrote block to device.
btape: btape.c:631-0 Wrote 1 EOF to "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:601-0 Rewound "HP-Ultrium3000" (/dev/nst0)
Done appending, there should be no I/O errors
Doing Bareos 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 Bareos 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 Bareos 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.
Bareos 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:601-0 Rewound "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:838-0 Wrote first record of 64412 bytes.
btape: btape.c:849-0 Wrote second record of 64412 bytes.
btape: btape.c:860-0 Wrote third record of 64412 bytes.
btape: btape.c:631-0 Wrote 1 EOF to "HP-Ultrium3000" (/dev/nst0)
btape: btape.c:876-0 Backspaced over EOF OK.
btape: btape.c:881-0 Backspace record OK.
btape: btape.c:899-0
Block re-read correct. Test succeeded!
=== End Write, backup, and re-read test ===
=== Forward space files test ===
This test is essential to Bareos.
I'm going to write five files then test forward spacing
