In reality the only "formatting" that takes place on these partitions is when you run the mdadm command: It combines the partitions according to your command line arguments, producing a new block device, /dev/mdX. It's /dev/mdX that you format (or put LVM on, then create a physical volume.. then a volume group... then a logical volume... then format that with a filesystem). -- Brendan Conoboy / Red Hat, Inc. / blc@redhat.com
