This is getting weirder. The mt eof, rewind and status commands work. The tar
command failed.
root@dl160g11:/opt/bacula/etc# mt -f /dev/st0 eof
root@dl160g11:/opt/bacula/etc# mt -f /dev/nst0 rewind
root@dl160g11:/opt/bacula/etc# mt -f /dev/nst0 status
SCSI 2 tape drive:
File number=0, block number=0, partition=0.
Tape block size 0 bytes. Density code 0x5c (LTO-7).
Soft error count since last status=0
General status bits on (41010000):
BOT ONLINE IM_REP_EN
root@dl160g11:/opt/bacula/etc# tar zcf /dev/nst0 /opt/bacula ; echo "Error
code: $?"
tar: Removing leading `/' from member names
tar (child): /dev/nst0: Cannot write: Input/output error
tar (child): Error is not recoverable: exiting now
tar: /dev/nst0: Wrote only 4096 of 10240 bytes
tar: Child returned status 2
tar: Error is not recoverable: exiting now
Error code: 2
I'm wondering if I need to try something other than Ubuntu 22.04.
