[Users] Opinions needed: 3 node gluster replica 3 | NFS async | snapshots for consistency

I'm looking for some opinions on this configuration in an effort to increase write performance: 3 storage nodes using glusterfs in replica 3, quorum. Ovirt storage domain via NFS Volume set nfs.trusted-sync on On Ovirt, taking snapshots often enough to recover from a storage crash Using CTDB to manage NFS storage domain IP, moving it to another storage node when necessary Something along the lines of EC2's data consistency model, where only snapshots can be considered reliable. The Ovirt added advantage would be memory consistency at time of snapshot as well. Feedback appreciated, including 'you are insane for thinking this is a good idea' (and some supported reasoning would be great).
