Show stats will let
you look at per volume IO.
stats
show -i 15 -e volume:(volumes):(nfs)
Replace volumes with something that matches all the
volume names, -e means it’s looked at as a regular expression.

Subject: High CPU utilizations and
file I/O
Hi all,
From some days the CPU of a 3020C reaches 100% slowing down all
processes.
Maybe some area of a 3020HA is stressed on I/O.
There’s a VMware on NFS farm using both servers and VDI also! The
customer states that in the NFS volume for VMware there’s an high
activity of continous destruction and building of VMware vdisk…
Is there some tool that can let me understand which volume is under
stress and in case move it on the other head?
Or maybe this filer is undersized for the job that has been
asked…
