Hi
I need some example to configure nfs4 mandatory locking.
I have setup nfs4 server and client.
I want to enable mandatory locking so that no two clients can access
file at same time.
Please guide me.
I working on ubuntu 10.04 and kernel 2.6.32-21-server.

Thanks and Regards,

What exactly do you mean by "mandatory locking", and why isn't advisory
fcntl-based locking sufficient?

The Linux client and server don't really support mandatory locking.
If that's a problem, then we'd need to understand why exactly you need
this, and why advisory locking isn't sufficient.
