</span>I use gfs2 quite a bit, but not nfs.<br>
<br>
Can I make a suggestion? Don't use gfs2 for this.<br>
<br>
You will have much better performance if you use an active/passive<br>
failover with a non-clustered FS. GFS2, like any cluster FS, needs to<br>
have the cluster handle locks which is always going to be slower (by a<br>
fair amount) than traditional internal FS locking.<br>
<br>
The common NFS HA cluster setup is to have the cluster promote/connect<br>
the backing storage (drbd/iscsi), mount the FS, start nfs and then take<br>
a floating IP address.<br>
<br>
GFS2 is an excellent FS for situations where it is needed, and should be<br>
avoided anywhere possible. :)<br>
