It sounds then like this error existed before the Bacula upgrade. Are you encrypting your backups with the LTO native drive encryption? Could the tape have been originally labelled and used with an encryption key loaded, which was then changed (or removed) causing the tape to become unreadable? Are you trying to recover data from this tape, or are you just trying to work out why it is not working? If you don't need to recover data from it, I'd suggest rewinding the tape and writing some EOF marks to make the tape look empty, then relabelling it through Bacula. If the tape is in good condition, this should allow it to be reused, but of course doesn't explain what happened in the first place for it to get into this state. > btape: btape.c:612-0 Wrote 1 EOF to "LTO-7" (/dev/nst0) > btape: btape.c:1219-0 Rewind OK. > 29-Dec 11:19 btape JobId 0: Fatal error: block_util.c:425 Volume data > error at 0:0!

I'm not familiar with exactly how btape works, but this suggests that writing the labelling block failed - the data written could not be read back again. It suggests something wrong with the tape. Presumably if you ran this test with another tape then it would complete successfully. If you have IBM's diagnostic tools installed (itdt) you could see whether that has anything you can run to check the health of the tape. I'm not familiar with IBM's tools, but the HP Tape Tools diagnostic does have a test for tape quality.
