Hello,

Please take out the:

Hardware End of File = no

and

Device Type = Tape

then try the test again.  If it fails please post the btape output, the OS you are running, the Bacula version, and where you got the binaries.

Best regards,

Kern

Hello,

I am attempting to use Bacula on a backup server and am having trouble with btape test in the append files section. I have read the documentation, searched on Google, and updated the firmware on my SAS card and tape drive. I don't see any particularly helpful log messages on the system. Any thoughts on where I should look to continue troubleshooting this? Could it have something to do with the SCSI driver in the OS?

Configuration is as follows: Debian 8 with Atto H1280 (also tried H644) SAS HBA and HP LTO6 tape drive. More details below.

Thank you.

Best,

Aaron

Output from btape:
=== 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:582-0 Rewound "LTO-6" (/dev/nst0)
btape: btape.c:1917-0 Wrote one record of 64412 bytes.
btape: btape.c:1919-0 Wrote block to device.
btape: btape.c:612-0 Wrote 1 EOF to "LTO-6" (/dev/nst0)
btape: btape.c:1917-0 Wrote one record of 64412 bytes.

btape: btape.c:612-0 Wrote 1 EOF to "LTO-6" (/dev/nst0)
btape: btape.c:478-0 open device "LTO-6" (/dev/nst0): OK
btape: btape.c:582-0 Rewound "LTO-6" (/dev/nst0)
btape: btape.c:1430-0 Now moving to end of medium.
btape: btape.c:633-0 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:1917-0 Wrote one record of 64412 bytes.
btape: btape.c:1919-0 Wrote block to device.
btape: btape.c:612-0 Wrote 1 EOF to "LTO-6" (/dev/nst0)
btape: btape.c:582-0 Rewound "LTO-6" (/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=5, blocks=7, bytes = 451,136
End scanning the tape.
We should be in file 4. I am at file 5. This is NOT 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.

bacula-sd.conf (I tried this without the Hardware End of File line; same result):

  AutomaticMount = yes;               # when device opened, read it
  AlwaysOpen = yes;
  RemovableMedia = yes;
  RandomAccess = no;
  Maximum File Size = 5GB
  Hardware End of File = no
}
