RE: My F820 is slow ....

You said you had more than one volume ?. Were the disks all added at the same time ?. That is, you have not added a disk to an existing volume?. Is the activity read or write activity or a mix ?. Can you post up a sysstat output ?. Try using 'statit' which will indicate if a specific disk is being hammered. If this is the case then it would mean that a disk was added to the volume group after vol creation and normal stripping is not in effect. -----Original Message----- From: Mike Horwath [mailto:drechsau@visi.com] Sent: Friday, 1 November 2002 10:11 To: Mike Ball Cc: 'Pawel Rogocz'; toasters(a)mathworks.com Subject: Re: My F820 is slow ....

Hey Clarence, Filer MRTG is great, we run it now even with Datafabric Manager running as well. It isn't very good for performance analysis but great for monitoring filesystem usage and particularly snapshots if you are doing any snapmirroring.

The instructions can be found at http://now.netapp.com/NOW/download/tools/filer-mrtg/. It "provides a current and historical view (the last day, week, month, and year) of statistics for network traffic, CPU load, disk usage, and NFS and CIFS operations." -- Clarence. > thanks, > > > Pawel

How many disk shelves have you got? How many FCAL's you got? Running any database devices on the filer? What size raid groups have you got? Especially for databases. Running any gigabit interfaces on Sun boxes? Was the system running fast for a long period then suddenly performance dropped or has it been gradual degradation? Does a netdiag -v report any unusual NFS or application errors? I have many more questions as I am going through something similar right now. Hopefully we can help each other.

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 -----Original Message----- From: Pawel Rogocz [mailto:pawel@rogocz.com] Sent: Friday, November 01, 2002 5:24 AM To: toasters(a)mathworks.com Subject: My F820 is slow .... 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 --

Pawel, Have you grown your volumes lately? If so, how many disks did you add to the volumes when you grew them? I have seen customers who have volumes that are at 90%-95% and they add one or two disks to increase the disk space for the volume. What this does is creates a hot spot where any new writes going to those volumes only gets written to the 1 or two disks which were added = bad performance because WAFL is not able to stripe across all the disks in the volume.

optimum setting for Solaris8 and nfs/netapps
by Daniel Finn 30 Oct '02

30 Oct '02

What are the best options to use when trying to get the best performance and good stability out of a Solaris8 server mounting volumes via nfs from a F740/F760? Thanks Dan I've already made sure that the network connection for the Solaris server is 100MB fdx.

If what you're looking to do is make it forget that it's part of a cluster, you can try the following (which worked for us on some 760c's - I've never used/seen a 600 series though). At the ok prompt, do unsetenv partner-sysid Davin.
