Once you change sd[ab]6 to partition ID to fd (Raid auto detect), just run (of the top of my hand... I'm not sure... Check the mdadm man page): $ mdadm --build --level=0 --raid-devices=2 /dev/hda6 /dev/hdb6 (Change to --level=1 if you want RAID1) You -may- need to run: (Again, check the man pages) $ mdadm --assemble /dev/md0 /dev/sda6 /dev/sdb6 -Gilboa -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list
