You to make it a 2-drive array you need a recent 2.6 kernel and a recent release of mdadm. If you have these, then mdadm -S /dev/md2 # shutdown md2 and release hde1 mdadm /dev/md1 -a /dev/hde1 # add hde1 as a spare in md1 mdadm -G -n2 /dev/md1 # grow md1 to have two devices. If you don't have 2.6, then you will have to recreate md1 with the desired number of components, which will require unmounting it. mdadm -S /dev/md2 mdadm -S /dev/md1 mdadm -C /dev/md1 -l1 -n2 /dev/hdc1 missing mdadm /dev/md1 -a /dev/hde1 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
