Showount was my suggestion too, but I had a user swear to me that wasn't giving an accurate listing. Maybe because we soft mount things?
showmount isn't reliable. and, with lots of clients and lots of mounts, it can be a performance issue.
we disable the collection of rmtab stats by setting option nfs.rmtab.persist off.
the ways I look to see what clients are using an export include. - sweep all the clients and check /proc/mounts - unexport the share and wait for phone calls ;-)

Thanks for that suggestion, Jeff. I was hoping the filer was keeping track of things somewhere...
Best, Matt

The showmount command will show what is exported from the filers to the clients.
I'm not sure if it is the most reliable way, but you can enable the options nfs.per_client_stats.enable and then run "nfsstat -h" on the filer and look for "Client".
The per client stats can add some load to the filer so many people don't leave it on all the time. It looks like it will only show 256 clients according to the man page.

How about showmount -a<filer name>

This is probably a silly question, but what is the most reliable way to get a list of NFS clients that have an export mounted? OnTap 7.3.3, and the share is exported R/W to the world.
Thanks, Matt
