List-Post: List-Help: List-Subscribe: , List-Archive: looks like you are getting the maximum number of nfs operations by mountpoint. See nfs.sourceforge.net The maximum nfs operations by mountpoint for kernel < 2.5.47 is 256 I?m getting the same problem with kernel 2.4.20. I ipgraded a nfs client to kernel 2.6 and I still getting the same problem. Maybe a solution is to upgrade the server and client to kernel 2.6 (I didnt tested it yet) - Fabiano ----- Original Message ----- From: "Brasseur Val?ry" To: Cc: Sent: Tuesday, March 16, 2004 8:35 AM Subject: [NFS] linus 2.4.20 nfs performance problem I have a config where LInux machines (bi Xeon 2.4Ghz 2Gb memory, kernel 2.4.20 + trond patch) are accessing a Netapp 810 (or 825) there is a lot of process (#400) when in load a lots of process are in D state, the filer are around 5000 nfsops and the network is near 50 mbit/s for each machine the machine and the filer are connect by a switch, machines are at 100mb and filer is at 1Gb the cpu on the machines are near &?% and load average is near 100 or more I don't know where is the bottleneck... is somebody can help me ? thanks in advance valery ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
