Judging from the "BB02" string, I suspect it to be a
problem with the block size. I've had such problems
when I first deployed Bacula, so I ALWAYS set the
block size before I mount a tape, and also after I
eject it.
Here's my set_blocksize.sh script:
8<--cut-here----------------
#!/bin/sh
# Set variable block mode (BlockSize = 0)
# Fixed block (BlockSize <> 0) is WRONG!
# If in doubt, run tapeinfo -f /dev/sg0 - BlockSize
should be 0
mt -f /dev/nst0 defblksize 0
# Rewind the tape
mt -f /dev/nst0 rewind
---------------cut-here-->8
Here's my eject_tape.sh script:
8<--cut-here----------------
#! /bin/sh
cd /etc/bacula
# Set variable block mode
# If in doubt, run tapeinfo -f /dev/sg0 - should be 0
mt -f /dev/nst0 defblksize 0
# Rewind the tape
mt -f /dev/nst0 rewind
# Eject the tape
mt -f /dev/nst0 eject
exit 0
---------------cut-here-->8
While I'm at it, here's tape_properties.sh ...
8<--cut-here----------------
#! /bin/sh
tapeinfo -f /dev/sg0
exit 0
---------------cut-here-->8
... and clear_label.sh:
8<--cut-here----------------
#!/bin/sh
# Manually relabel a tape.
#
# Run bconsole
# unmount
# delete media volume
# Set variable block mode
# If in doubt, run tapeinfo -f /dev/sg0 - should be 0
mt -f /dev/nst0 defblksize 0
# Rewind the tape
mt -f /dev/nst0 rewind
# Write physical End Of File (EOF) to the tape
mt -f /dev/nst0 weof
# Run bconsole
# label
# mount
---------------cut-here-->8
