We use RHCS with Quorum disk or a third node for quorum.
Coming from HP-UX world, we miss a concept of a Quorum Server and it would be very beneficial for us
Our experience with quorum disk is not good as it's very sensible to Storage response times and timeout adjustments. Furthermore, a quorum disk cannot be used for environments requiring replicated storage
On the other side, having a third node for the quorum is more robust but very expensive when there is a big amount of clusters in the company (at least one virtual machine per cluster)
Having the ability to use a separate RHCS offering quorum services for a big amount of clusters in the company would be really helpful
