See the manpage and other documentation for mdadm and of course double-check the device names you want, but this is what I have done in the past: # create the array mdadm -C /dev/md2 -l 10 -c 128 -n 4 /dev/sd[c-f] # add it to the config mdadm --examine --scan | grep md2 /etc/mdadm.conf JN

In that case, you can create a RAID10 in a single step like this: mdadm --create /dev/md0 --level=raid10 --raid-devices=4 /dev/sda /dev/sdb /dev/sdc /dev/sdd Hope this helps, Florian Philipp signature.asc Description: OpenPGP digital signature
