<div>Hi,<br>
</div>
<div><br>
</div>
<div>can someone point me at a good source to help me understand
nufa. I've checked on the mail list archive, and gluster.org
and can't find a lot of detail.<br>
</div>
<div><br>
</div>
<div>What I'd like to understand is whether nufa an option only
for gluster client mounts, or can nufa be used when the client
access protocol is nfs?<br>
</div>

Hi Paul,<br>
NUFA works irrespective of the access protocol. If a client happens
to be mounted on one of the server (brick) nodes, then all new files
created from that client (and further writes to the file from any
client) will always go that local brick, irrespective of which brick
the file name actually hashes to. There is a 'dht-link-to' file on
the hashed brick, but all data resides on the local brick.<br>
<br>
You can enable NUFA with `gluster vol set <volname>
cluster.nufa on`. Not sure why it is not listed inthe gluster vol
set help command. (Perhaps it's not maintained?)<br>
Hope this helps.<br>
