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. 11-Sep 14:43 bls JobId 0: No slot defined in catalog (slot=0) for Volume "TEE016L6" on "Drive-1" (/dev/sa0). 11-Sep 14:43 bls JobId 0: Cartridge change or "update slots" may be required. 11-Sep 14:43 bls JobId 0: Ready to read from volume "TEE016L6" on device "Drive-1" (/dev/sa0).

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--------- 0: 0x5a variable 0 0x1 1: 0x5a variable 0 0x1 2: 0x5a variable 0 0x1 3: 0x5a variable 0 0x1 --------------------------------- Current Driver State: at rest. --------------------------------- File Number: 0Record Number: 0 Residual Count 0 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 "˜êÇ". Buffer discarded. How do I fix this? — Kind Regards, Sidsel Jensen
