The mount options is useful to know.  I have moved over to centos 6.2 
since F17 was freezing up on me every 10 to 12 hours.

I am guessing I will need to wait for CentOS 6.3 to get direct IO 
support and hopefully live snapshots as well.  I might test glusterfs as 
well.  PS I use localhost:/volumename for NFS.
