The btape output is below. I'm running Debian 8.8 (kernel 3.16.0-4-amd64). I downloaded the Bacula 9.0.1 source from https://sourceforge.net/projects/bacula/files/bacula/9.0.1/ and compiled the binaries on my machine. The binaries are dynamically linked, so I added "/home/agreenblatt/software-bacula/bacula/src/stored/.libs" to /etc/ld.so.conf.d/bacula.conf and ran ldconfig. I assume that the warning about plugins in /usr/local/lib can be ignored as a result? (Though, now that I look, I see the libs are indeed in /usr/local/lib, so perhaps I didn't need to make the extra file in ld.so.conf.d.)

Best,

Aaron

=== 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 ...

=== 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: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.



=== Forward space files test ===

This test is essential to Bacula.

I'm going to write five files then test forward spacing
