+# There are six resource agent types used: ganesha_mon, ganesha_grace,
+# ganesha_nfsd, IPaddr, and Dummy. ganesha_mon is used to monitor the

+# the remaining ganesha.nfsds into grace. ganesha_nfsd is used to start
+# and stop the ganesha.nfsd during setup and teardown. IPaddr manages
+# the VIP. A Dummy resource named $hostname-trigger_ip-1 is used to
