Thanks for the tips...unfortunately, making the changes you suggest (removing timeo, rsize, wsize options) doesn't seem to address the issue with MPICH2 and NFSv4. Greg Quoting Trond Myklebust <Trond.Myklebust@xxxxxxxxxx>:
This is getting to be a FAQ... 2 second timeouts over TCP are just plain wrong: they will cause you to continuously disconnect and reconnect (as 'netstat -t' is bound to show you). Please don't muck with the default timeo=600. There is also no reason to mess with rsize and wsize: allow the client and server to autonegotiate.
