So you want to setup a ping ressource in each subnet. if your active node can not reach the ping node in one subnet, its an indication, that the node have lost its connectivity in that network.

The secondary server is  to be a failover if the server goes down or if any of the Ethernet ports become disconnected for any reason.  I read through the documentation and I am still not sure of the relationship between the Corosync hostnames / interfaces and Pacemaker resources.  Could corosync be configured to detect failure and start failover of a node using rrp or does the resource need to be monitored by Pacemaker in order to get moved form primary to secondary server?
