It looks like raid10 module provides all the functionality of raid1 too. For example, for a 2-component raid1 array, the two: mdadm -C -l1 -n2 /dev/md1 /dev/sda1 /dev/sdb1 and mdadm -C -l10 -n2 -ln2 /dev/md1 /dev/sda1 /dev/sdb1 will create the same array. Ditto for e.g 3-component raid1: mdadm -C -l1 -n3 /dev/md1 /dev/sd{a,b,c}1 and mdadm -C -l10 -n3 -ln3 /dev/md1 /dev/sd{a,b,c}1 will do the same. Shouldn't raid1 module be removed from kernel? :) /mjt
