[ClusterLabs] Puppet and Pacemaker

[Gavin Main]

Thanks Tomas. I am stuck with RHEL 6.5/6.6 for the moment, so it looks like I need to get creative. Using the id to specify the rule ID appears to help.

pcs constraint location ha_vip rule constraint-id=yourId score=-INFINITY id=location-ha_vip-1-rule pingd lt 1 or not_defined pingd
