Did you create /etc/mdadm.conf ? echo "DEVICE /dev/sd*" > /etc/mdadm.conf mdadm --brief --examine /dev/sd* >> /etc/mdadm.conf Check the raid with cat /proc/mdstat It tells you which devices are part of the array. Finally put the raid flag on the partitions. I'm not sure whether it's really needed, I just do it: parted /dev/sda set 1 raid set 2 raid print 1 0.031 101.975 primary ext3 boot, raid 2 101.975 194474.355 primary raid quit Theo
