Raid math: RAID(5+0) == RAID(5) + RAID(0) Commands: mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sda /dev/sdb / dev/sdc mdadm --create /dev/md1 --level=5 --raid-devices=3 /dev/sdd /dev/sde / dev/sdf mdadm --create /dev/md3 --level=0 --raid-devices=2 /dev/md0 /dev/md1 I believe this is all amply documented on a variety of md websites.
