症状

The following command can list all mount points in the form of :host:dirpath: 
showmount -a
Regarding the use of this command, the recommendation from Support is to not use it, as it is not a reliable way to monitor connections.
  • It only provides specific information from the specific node 10 Minutes ago, so it is never up to date.
  • If the mount command has any sort of issues related to the client that is connecting, even if it works, it does not show up in showmount.   
  • The showmount does NOT show any NFSv4 connections, only v3.

原因

There are no commands or other ways to get accessing NFS mountpoints on each node in a cluster. There are access zones and many IPs on Isilon nodes.

解决方案

To verify current statistics:

This command shows the count of all the connected and active clients: 
isi statistics query current --nodes=all --stats=node.clientstats.connected.nfs,node.clientstats.active.nfs,node.clientstats.active.nfs
This command also shows the NFS clients, but they are the active clients only and not showing all NFS clients including inactive but NFS mounted clients. 
# isi statistics client --nodes=all --protocols=nfs3
