You don't have pingd for monitor the gateway for your plublic Network
you can find an example in this link

> I have a few clusters that we are about to put into production.
> One of the tests was to pull the public network cable on the
> node that hosted the Virtual IP for the Cluster.
> We did and the Virtual IP didn't move. It stayed on the node originally
> selected.
>
> Now, I'm thinking that I don't have the configuation setup correctly.
>
> Setup: 3 to 5 nodes. Two Private switches for corosync/pacemaker
> communications.
> Active-Backup Bond into the private switches.
>
> Public Interfaces of all the nodes on the same network and pingable
> between them.
