This is most likely not a configuration issue. However I see two
unrelated problems in your configuration.

" Action On Purge = Truncate" I believe is for disk pools.

Also replace /dev/st0 with /dev/nst0. /dev/st0 can cause your tapes to
be corrupted by being rewound without bacula knowing.

Bacula believes a tape is full if it hits any errors when writing.
Check your dmesg output for scsi errors.
