+# Each participating node in the cluster is assigned a virtual IP (VIP)
+# which fails over to another node when its associated ganesha.nfsd dies
+# for any reason. After the VIP is moved to another node all the
+# ganesha.nfsds are send a signal using DBUS to put them into NFS GRACE.
+#
+# There are six resource agent types used: ganesha_mon, ganesha_grace,
+# ganesha_nfsd, IPaddr, and Dummy. ganesha_mon is used to monitor the
+# ganesha.nfsd. ganesha_grace is used to send the DBUS signal to put
+# 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
+# ensure that the NFS GRACE DBUS signal is sent after the VIP moves to
+# the new host.
