This doesn't work because the array wasn't made from partitions. I suggest you recreate the array using partitions and see how that goes: mdadm -C /dev/md6 -l5 -n6 -x1 /dev/sd[cdefghi]1 NeilBrown - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
