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
I tested the autochanger with the commands:
/usr/libexec/bacula/mtx-changer /dev/sg3 listall 0 /dev/nst0 and got the
following output:
D:0:F:1:PT7789L3
S:1:E
S:2:F:PT7784L3
S:3:E
S:4:F:CLN002L1
S:5:F:PT7783L3
S:6:F:PT7788L3
S:7:E
S:8:F:CLN001L1
S:9:F:PT7782L3
S:10:F:PT7787L3
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
tried to move tapes into the drive
/usr/libexec/bacula/mtx-changer /dev/sg3 loaded 0 /dev/nst0 0
1
and back to the slot
/usr/libexec/bacula/mtx-changer /dev/sg3 unload 1 /dev/nst0 0
Unloading drive 0 into Storage Element 1...done
this all seems to work all right, but If I try btape:
the tape seems to be ok (I have previously loaded it with mtx-changer),
but the autochanger test fails with the error:
3301 Issuing autochanger "loaded" command.
3991 Bad autochanger command: /usr/libexec/bacula/mtx-changer /dev/sg3
loaded 1 /dev/nst0 0
3991 result="": ERR=Child died from signal 9: Kill, unblockable
You must correct this error or the Autochanger will not work.
I enabled debugging in mtx-changer.conf and noticed a lot of not ready
messages like these:
20130415-17:17:17 Doing mtx -f /dev/sg3 load 1 0
20130415-17:18:11 Device /dev/nst0 - not ready, retrying...

20130415-17:47:01 Doing mtx -f /dev/sg3 0 -- to find what is loaded
20130415-17:48:49 Parms: /dev/sg3 loaded 0 /dev/nst0 0
how can I manage? may someone help please?
the only "strange" thing I did is that as I have not yet LTO4 RW barcode
labels I used LTO3 RW ones, but may this be the cause of not ready messages?
kind regards

=== 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.

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
loaded 1 /dev/nst0 0
3991 result="": ERR=Child died from signal 9: Kill, unblockable
You must correct this error or the Autochanger will not work.
