has anyone got a pacemaker agent for BigIP I want a pacemaker Corosync cluster to control the BigiP fail-back during an outage recovery

I am looking for help for ways to get a Pacemaker/Corosync HA Linux Cluster to interoperate with our BigIP api's. Specifically I want to make sure that a replicated database controlled by Pacemaker/Corosync is fully populated before the BiGIP fails the service back from the standby datacenter to the live data centre after a service recovery. Has anyone got a Pacemaker Agent that might give some pointers or is there a better way?

Thanks all
