Thanks for the reply. If that is the case, why wouldn't all 5 of the drives
in the system also indicated this secondary type as ext2? The only entry in
the table with this indication is the new addition.
i.e. /dev/sdb1: LABEL="/usr2" UUID="8h3982d7-0aec-3856-3cb4-221c5d22a8d5"
TYPE="ext3"

Thanks for the input.
