[ILUG] Why does NFS on Linux suck rocks?

[Niall O Broin]

Specifically, why is that that when a server disappears, the clients 
get stale NFS file handles even when the server has come back? A key 
point of NFS is its clientside statelessness. Of course, this is how it 
has worked on Sun boxes since forever - an NFS server could go away, 
and the client would work away happily, and would carry on where it 
left off whenever the server came back.  I won't be surprised to be 
told that Linux has "improved" NFS so that this is no longer true, but 
I hope somebody will be able to tell me how to unimprove it so that I 
don't screw upp all my NFS clients when I need to reboot the server.
