Hello list,
I have always problems with my tape drive and Bacula. A problem
resolved, another appears.
I'm despaired to make this drive working with Bacula ... this is my last
mail before I plan to backup on disk only (which is a pity enough ..).
First my complete configuration :
OS: Linux (Debian) with kernel 2.6.15
Bacula: 1.38.9 with PostgreSQL (8.1.4)
Tape drive:
Sony SDX-500C (AIT2)
phoenix:/var/backups# cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: SONY Model: SDX-500C Rev: 0204
Type: Sequential-Access ANSI SCSI revision: 02
Scsi:
phoenix:/var/backups# cat /proc/scsi/aic7xxx/0
Adaptec AIC7xxx driver version: 7.0
Adaptec 2940 Ultra SCSI adapter
aic7880: Ultra Wide Channel A, SCSI Id=7, 16/253 SCBs
Tape drive is on ID 06:

This is the problem I currently have :
I followed the bacula documentation about "variable block size" (setblk
0) and to init the drive correctly under linux (stoptions 7).
Here are the full operations I made:
phoenix:/etc/bacula# mt -f /dev/nst0 setblk 0
phoenix:/etc/bacula# mt -f /dev/nst0 stoptions 7
phoenix:/etc/bacula# mt -f /dev/nst0 rewind
phoenix:/etc/bacula# mt -f /dev/nst0 weof
phoenix:/etc/bacula# mt -f /dev/nst0 rewind
phoenix:/etc/bacula# mt -f /dev/nst0 status
drive type = Generic SCSI-2 tape
drive status = 822083584
sense key error = 0
residue count = 0
file number = 0
block number = 0
Tape block size 0 bytes. Density code 0x31 (unknown).
Soft error count since last status=0
General status bits on (41010000):

I'v read the bacula doc at least 3 times (especially the FAQ and the
Testing your drive with Bacula)
After this reading I ran the same job with the following options in
bacula-sd.conf :
- First with BlockPositioning = no, without success
- Second with MinimumBlockSize = 1024 and MaximumBlockSize = 1024,
without success
- Third with MinimumBlockSize = 1024 and MaximumBlockSize = 1024 and
BlockPositioning = no, without success
!! Important: the "btape test" completes successfully (with /dev/nst0).
I also did a "btape fill", with success too.
I'm 100% sure that the tapes are ok (they are new) and I've cleaned the
tape too ... The scsi cable should be OK, the jobs never fail
Any idea before I throw this drive through the window ... ?
In advance thanks, and sorry for my poor english
