2 node cluster with SLES12 SP1. No resources added at this point, fresh cluster that is online. We have an existing apache 2.4.x webserver on a cluster node. It has a number of websites, php, SSL and reverse proxy. The other node of the cluster has apache installed along with the php modules. Hawk is up and running so we can use that if needed to add the existing apache resource. My question is, how exactly do i add the existing apache resource to the cluster?
