[Pacemaker] IP fail over without controlling the services

Hi,

I'm trying to set up IP auto fail over on a two-way master-slave MySQL
replication cluster. What I'm trying to achieve is to only fail over the
IP when there's a problem on the mysqld service. I don't want pacemaker
to control the mysqld service. 

With my current configuration, pacemaker will always keep the service
running on the active node and the service stopped on the passive node.

Any help would be much appreciated.
