[CentOS] NFS exporting a GFS mount point

Hello,

I have a storage offering some 11 TB of space.  I'd happily use ext3 
and NFS export to 4 client machines, but 8 TB seems to be the tested 
maximum.  I'd really like one mount point for the whole 11 TB.  Since 
GFS offers lock_nolock option for local mounting, I'm assuming it's not 
so out of line to NFS export this GFS mount point.

Thoughts and inputs appreciated.
