[one-users] Error "Stale NFS file handle"

[Matthew Patton]

All of your NFS exports should have 'fsid=<N>' in your parameters.
I would surmise the NFS client is trying to use NFS v4 and the server  
doesn't understand it or doesn't handle it gracefully.
Force the server to only export as NFS v3 or v2 and likewise force your  
clients to only use v2 or v3.

Doing a loopback copy is pointless. Manually do a copy at a client machine  
 from the NFS server and see how long it takes. (you can copy it to  
/dev/null if you like).

Once that is confirmed working, then you can see what's going on with NFS  
v4.
