# 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.
