<div dir="ltr">I'm looking for some opinions on this configuration in an effort to increase write performance:<div><br></div><div>3 storage nodes using glusterfs in replica 3, quorum.</div><div>Ovirt storage domain via NFS</div>
<div>Volume set nfs.trusted-sync on</div><div>On Ovirt, taking snapshots often enough to recover from a storage crash</div><div>Using CTDB to manage NFS storage domain IP, moving it to another storage node when necessary</div>
<div><br></div><div>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.</div><div>
<br></div><div>Feedback appreciated, including 'you are insane for thinking this is a good idea' (and some supported reasoning would be great).</div><div><br></div><div>Thanks,<br><div><br></div><div><br></div><div>
