If it is performance related take a look at this document: http://www.redhat.com/f/pdf/rhel/Oracle-10-g-recommendations-v1_2.pdf I know this is for Oracle, but take a look at the default scheduler and other things in the document we are running Oracle databases off of NetApp NAS devices and had terrible performance issues and this document solved a lot of those. If you Google NFS performance issues Red Hat 5 you will see the kernel has a lot of issues that are said to be fixed, but never seem to be actually corrected. To turn NFSv4 off you should be able to: Add the this line to /etc/sysconfig/nfs RPCNFSDARGS="-N 4" Then restart nfs Stop rpcidmapd service and chkconfig it off Matt From: [email protected] [mailto:[email protected]] On Behalf Of [email protected] Sent: Wednesday, October 27, 2010 10:43 AM To: [email protected] Subject: RHEL 5.0 NFS Hello We have Linux servers with RHEL 4.0x version running nfs version 3 has nfs servers. We have added new servers with RHEL 5.0 version. When I do ps -ef | grep nfs I see that nfsd4 is started . We are facing lot of nfs issue on dir which are shared from RHEL 5.0. Please help me disable nfs version 4 if by default started in RHEL 5.0 so that we can use nfs version 3 in RHEL 5.0.
