[ovirt-users] Two Hosts with Self Hosted Engine - HA / Failover & NFS

Is it possible to have only two physical hosts with NFS and be able to do VM HA / Failover between these hosts? Both hosts are identical with RAID Drive Arrays of 8TB. If so, can anybody point me to any docs or examples on exactly how the Storage setup is done so that NFS will replicate across the hosts? If not what file system should I use to achieve this? Thanks Shane
