mdadm --add /dev/md0 /dev/sdh1
hdparm -S 180 /dev/[sh]d[a-z] # makes disks to stop spining after 15 mins of inactivity
Add this command to the end of the file /etc/rc.d/rc.local to ensure that it is executed every time the system is booted:
<nowiki>#!/bin/sh
#
# This script will be executed *after* all the other init scripts.
# You can put your own initialization stuff in here if you don't
# want to do the full Sys V style init stuff.
touch /var/lock/subsys/local
