Hi Paul, look's like you didn't get the LVM architecture :-(. You can't add a drive to a LV, no matter how brand new and shiny it is and no matter how deprerate you try. If you read the LVM-HOWTO's from the beginning, you'll see that LVM is collecting physical-volumes ( your drives or partitions on drives ) in logical volume groups ( so called VG's, your ide_disks ) which are the home of the logical volumes ( LV's, your bacula ). So, to be able to extend your LV to use the space on your new disk, you must first add the new disk to the VG with vgextend ( setting the partition-type is not enough :-) ). If this doen't work, do a pvcreate on the new disk first and try vgextend again.
