[ovirt-users] Guide for setting up GlusterFS geo-replication?

Is there an updated guide for setting up GlusterFS geo-replication? What I am interested in is having another oVirt setup on a separate server with glusterFS volume replicated to it. If my primary cluster went down I would be able to start important VMs on the secondary oVirt build until I'm able to repair the main cluster. In oVirt 4.2.5 clicking geo-replication > new in the volume GUI produces no results. Nothing happens when I click it (using multiple browsers). And under storage domains clicking remote data-sync -> setup produces a popup but just has a loading icon in the middle and never completes loading. Why are neither of these two features working for me?
