options nfs.tcp.recvwindowsize

I need to change this NFS parameter from 26280 to 64240 and would like to know if it's ok to carry out on the fly.

I have heard that there may be a momentary blip whilst it adjusts to the new setting.

Any advice will be welcomed.

Regards

Mark

I did it during a maintenance slot (OnTAP 7.2.5.1),

and there was no disturbance on running NFS clients.

I guess it will become effective for new NFS mounts - how to prove this?

Hi Michael,

Thanks for your experience on this matter.

I have recently implemented the change here with no discernable effects.

Thanks again for your help.
