[TriLUG] NFS client connections and stats

[Ron Kelley via TriLUG]

Greetings all,

I have a CentOS 6 server running NFSv3 with a number of exported directories.  Recently, one of the NFS clients started hammering the server, but I can't track down the client.  I have done a ton of googling, and the best tools I can find are "nfsiostat" and "nfsstat".  The best tool seems to be "nfsiostat", but I get the message "No NFS mount points were found".  The other tool just spits out some stats but nothing that links a client to an NFS mounted directory.

Hoping someone might have a solution to show which NFS client is consuming I/O.

Thanks.

-Ron
