Hi,
I'm trying to setup a backup server and face the following problem. I
already setup a Bacula system using a Exabyte VXA tape library. This
system is using a Seagate LTO library and I get this error when using
the tapes (only a small amount of data is written on the tape). The
tapes are before with another system (a windows backup system) and I
cleaned them all using the following script:
### begin cleanalltapes ###
#!/usr/bin/bash
### Where are the binaries
MTXCHANGER=/opt/csw/etc/bacula/mtx-changer
MTX=/opt/csw/sbin/mtx
MT=/usr/bin/mt
CHANGER=/dev/scsi/changer/c3t5d0
DRIVE=/dev/rmt/0
SVCADM=/usr/sbin/svcadm
SVCNAME=cswbacula
TIME="time -p"
### The script
echo "Disabling Bacula"
$SVCADM disable $SVCNAME
echo "Unloading current tape"
$TIME $MTX -f $CHANGER unload
for i in 1 2 3 4 5 6 7 8
do
echo "Loading tape $i"
$TIME $MTXCHANGER $CHANGER load $i $DRIVE 0
echo "Retension the tape"
$TIME $MT -f $DRIVE retension
echo "Writing 2 eof marks to remove the label"
$TIME $MT -f $DRIVE weof 2
echo "Rewinding the tape"
$TIME $MT -f $DRIVE rewind
echo "Unloading tape $i"
$TIME $MTXCHANGER $CHANGER unload $i $DRIVE 0
done
echo "Enabling Bacula"
$SVCADM enable $SVCNAME
### end cleanalltapes ###
I replaced the first rewind with a retension command but that doesn't
help.
loading the tape takes about 56.16 seconds
retension takes about 289.94 seconds
writing 2 eof takes about 7.19 seconds
rewinding takes about 0.02 seconds
unloading the tape takes about 36.72 seconds
I don't get any errors with this script.
this is the error when running a backup:

12-Aug 16:37 popa-dir: No prior or suitable Full backup found in
