We originally used pacemaker to move a VIP between our RGWs, but ultimately decided to go with an LB in front of them. With an LB you can utilize both RGWs while they're up, but the LB will shy away from either if they're down until the check starts succeeding for that host again. We do have 2 LBs with pacemaker, but the LBs are in charge of 3 prod RGW realms and 2 staging realms. Moving to the LB with pacemaker simplified our setup quite a bit for HA.
We use a similar setup, but without an extra load balancer host. Pacemaker is deployed on all hosts acting as RGW, together with haproxy as load balancer. haproxy is bound to the VIPs, does active checks on the RGW, and distributes RGW traffic to all of the three RGW servers in our setup. It also takes care for SSL/TLS termination.
With this setup we are also able to use multiple VIPs (e.g. one for external traffic, one for internal traffic), and route them to different haproxy instances if possible.
