RHEL 5.0 NFS

Hello

 

Thanks allot for info , this is not for oracle.

We have RHEL 5.0 as nfs servers and accessed over the network with RHEL
4.0 nfs clients.

It is performance issues or directly related to nfs4?

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

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.

 

 

 

Rgds
