Hi Pawel, We have an F880 (6.2.1) with about 10-20 Sun boxes connected to ours. We are experiencing the same type of slowdown and sysstat readouts. Our database volumes are running particularly slow. I am working with NetApp now to resolve this. Try the following set of commands;

Go into advanced mode on the filer (telnet in) Priv set advanced *you will see a star showing advanced mode filer*> statit -b leave for a few minutes filer*>statit -enc

an nfsstat -l shows a detailed usage of nfs on a per client basis This will give a detailed summary

Hope it helps,

Aaron

I run 6.2.1 on F820 and I have bunch of Sun boxes ( around 60 ) who do NFS mounts.

The filer has more than one volume and sometimes during the day the output of systat -x shows 100% disk util for a couple of minutes.

1. Is there a way to find out which volume/disk is causing bottleneck ? 2. Is there a way to find which client is causing the load to spike ? 3. Can disk util be monitored via SNMP ? I was not able to find anything in the MIB provided on NOW.

thanks,

Pawel --
