Hi I have several web servers that are attached to a Netapp (network appliance) unit via NFS-3. A few servers are 5.5 and a few are 6.1 for comparison testing. All seem to have lousy performance.
We have a similar setup and it runs smoothly. Can you define "lousy performance" ? Can you give more details on your network? Are you using Gig ethernet? And over what medium? Can you also try just copying a 100MB file from the filer to one of the web servers and record the time? Are you running nfsiod? When
going through the issues with Netapp, the reasons given were that we have too many GettAdr/Lookup requests compared to actual reads. So all the NFS IOPS are being used up by these requests. As soon as the webservers get busy, requests pile up. I have tried everything I can think of. The web servers are even mounted read only with no help. My current mount options are: filer:/vol/fvol31 /home/13/13 nfs ro,noatime,-r=32768,-T,-b,-R0,-i,-D2,-L 0 0
Mounting noatime for web servers is a good idea but... your "noatime" option has no effect on NFS mounts (check out the mount man page). You need "vol options no_atime_update" on the NetApp. Any advice for sysctl tunes or anything else would be
much appreciatted! Thanks Nicole
