# 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.
