Hi

I’ve been trying to restore from a tape, where the job was unfortunately purged from the Catalog in the bacula database.

I can restore from other tapes, without any problems inside bacula, so the data on the tapes should be OK.

But when using bls and bextract I keep getting the BB02 – buffer discarded error

bacula# bls -j -V TEE016L6 /dev/sa0

bls: butil.c:287 Using device: "/dev/sa0" for reading.

I do have the following two statements in my tape-dev.conf:

<snip>

 Minimum block size = 64000

 Maximum blocksize = 256000

</snip>

But it looks like my tape-drive is already set to variable mode:

bacula# mt -f /dev/sa0 status

Mode      Density              Blocksize      bpi      Compression

Current:  0x5a                 variable       0        0x1

---------available modes---------

2:        0x5a                 variable       0        0x1

3:        0x5a                 variable       0        0x1

Bextract gives the same error as bls:

/usr/local/sbin/bextract -i /tmp/gandalf-restore -V TEE016L6\|TEE017L6\|TEE019L6\|TEE002L6\|TEE000L6 /dev/sa0 /tmp/Gandalf

11-Sep 15:14 bextract JobId 0: Error: read_record.c:151 block.c:291 Volume data error at 0:1! Wanted ID: "BB02", got "˜êǍ". Buffer discarded.

How do I fix this?
