Hello everybody
I hope that someone can help me:
I'm trying to setup an HP MSL 2024 to work with bacula 5.0.0 (26 January
2010) - I installed it with yum using CentOS 6 base repository
notice that I have already added bacula user to tape group and issued
mtx-changer command on a shell logged as bacula user, and it works
the really strange thing is that if a issue a label barcode command in
bconsole it starts the label process, but the output of the process
return errors as if mtx-changer output is not returned to bacula:
here is the situation before issuing the label brcodes command - as you
can see there is PT7785L3 loaded from slot 11 in Drive 0
/usr/libexec/bacula/mtx-changer /dev/sg3 listall 0 /dev/nst0
D:0:F:11:PT7785L3
S:1:E
S:2:E
S:3:E
S:4:E
S:5:F:PT7783L3
S:6:E
S:7:E
S:8:E
S:9:F:PT7782L3
S:10:E
S:11:E
S:12:E
S:13:E
S:14:E
S:15:E
S:16:E
S:17:E
S:18:E
S:19:E
S:20:E
S:21:E
S:22:E
S:23:E
S:24:E
bacula correctly notice that the cartdrige in already in Drive 0 is from
slot 11 and try to unload it, ... but got timeouts and ERR=Child died
from signal 15: Termination
anyway the cartdrige is actually unloaded from the drive:
/usr/libexec/bacula/mtx-changer /dev/sg3 listall 0 /dev/nst0
D:0:E
S:1:E
S:2:E
S:3:E
S:4:E
S:5:F:PT7783L3
S:6:E
S:7:E
S:8:E
S:9:F:PT7782L3
S:10:E
S:11:F:PT7785L3
S:12:E
S:13:E
S:14:E
S:15:E
S:16:E
S:17:E
S:18:E
S:19:E
S:20:E
S:21:E
S:22:E
S:23:E
S:24:E
so it seems to me that mtx-changer is working but not sends it output to
bacula
any ideas? This actually is driving me crazy
thanks

here is a btape test output too:

=== 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,

This is an *essential* feature ...

Got EOF on tape.

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: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 "Drive-0" (/dev/nst0)
btape: btape.c:608 Wrote 1 EOF to "Drive-0" (/dev/nst0)
btape: btape.c:578 Rewound "Drive-0" (/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=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.
Skipping read backwards test because BSR turned off.
=== Forward space files test ===
This test is essential to Bacula.
I'm going to write five files then test forward spacing

Ah, I see you have an autochanger configured.
To test the autochanger you must have a blank tape
that I can write on in Slot 1.
Do you wish to continue with the Autochanger test? (y/n): y
=== Autochanger test ===
3301 Issuing autochanger "loaded" command.
3991 Bad autochanger command: /usr/libexec/bacula/mtx-changer /dev/sg3

3991 result="": ERR=Child died from signal 9: Kill, unblockable
You must correct this error or the Autochanger will not work.
