Hi Donny (and everyone else who uses NFS-backed storage)<br>
<br>
You mentioned that you get really good performance in oVirt and I am curious<br>
what you use for your NFS options in exportfs? The 'async'<br>
option fixed my performance issues, but of course this would not be a<br>
recommended option in a production environment, at least unless the NFS<br>
server was running with a BBU on the RAID card.<br>
<br>
Just curious. Thanks! :-)<br>
<br>
