# Short-Description: Start and stop the MD software RAID monitor

# Description: The mdmonitor service checks the status of all software

#	RAID arrays on the system.  In the event that any of the arrays

#	transition into a degraded state, it notifies the system

#	administrator.  Other options are available, see the mdadm.conf

#	and mdadm man pages for possible ways to configure this service.
