Oh?
fuel doesn't (currently) set up API services in pacemaker
Nor should it, IMO. Other than the Neutron dhcp-agent, all OpenStack
services that run on a "controller node" are completely stateless.
Therefore, I don't see any reason to use corosync/pacemaker for
management of these resources. haproxy should just spread the HTTP
request load evenly across all API services and things should be fine,
allowing haproxy's http healthcheck monitoring to handle the simple
service status checks.
