I have found some issues while trying to install two nodes with centos 6.6, oVirt 3.4 and cluster functionality. 1 - If you enable the gluster service in a cluster, when you install the hosts, the installation fails because it tries to install the gluster packages from Centos repository and a dependency problem is reported. Workaround: Install the package yum-plugin-priorities and set priority=1 in the /etc/yum.repos.d/ovirt-3.4-dependencies.repo, section glusterfs-epel. 2 - If you reboot the host, the service glusterd doesn't start at init, and host becomes non operational. Workaround: Manually set glusterd to start at boot, using for example ntsysv. Regards Federico
