Hi guys,
Just wondering if anyone had any experience with using Bacula and the
IBM TS3100 (ULT3580-TD4) autochanger with the 3573-TL LTO-4 tape drive?
I'm running Debian etch with Kernel 2.6.18-4amd64 and I have a IBM
TS3100 connected via SAS to a LSILogic SAS3801X with theIBM
lin_tape-1.10.0 driver. I'm using the Debian bacula stable package
(1.38.11-8) - I am considering trying the debian's unstable 2.2.6
version though - to see if this fixed my problem as described below.
I can control the device perfectly using the ibm's IBMtapeutil. I can
use programs like tar/star etc.. to dump directly to the device - which
is fine. I can set the library to auto load the next tape once the
previous one is full, but i'd rather use Bacula to control this and do
incremental backups etc..
When testing using btape I get the following:
btape ULT3580-TD4
Tape block granularity is 1024 bytes.
btape: butil.c:272 Using device: "ULT3580-TD4" for writing.
btape: btape.c:338 open device "ULT3580-TD4" (/dev/IBMtape0n): OK
*test
=== Write, rewind, and re-read test ===
I'm going to write 1000 records and an EOF
then write 1000 records and an EOF, then rewind,
and re-read the data to verify that it is correct.
This is an *essential* feature ...

Got EOF on tape.

I can query the tape position directly using the IBMtapeutil drive
without any problems:

Has anyone got a TS3100 working with bacula under linux?
Any thoughts or suggestions?
