Oggetto: Re: High CPU utilizations and file I/O

Let me ask one question.

Are the VMDK's aligned?


If Yes, continue with volume stats.

If No, stop everything, there's your problem, no way around it.

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…
