Hi,

I am using RHEL3 and RHEL4 boxes. what is the safest way to upgrade NFS version to latest NFS4? Is NFS kernel dependent? I mean to ask if i upgrade NFS version will i need to upgrade the kernel as well?

Due to some reasons i cant upgrade the OS to RHEL5. Can any body suggest me how to upgrade safely to NFS version 4?

Many thanks.

Hi,

nfs is provided by kernel module nfsd.ko, which will be handled by various user space tools.

Upgrading to a newer NFS version means upgrading kernel an various tools. Upgrading kernel will bring you up in upgrading glibc and various others, which means upgrading the rest of the system.

Sorry that i cannot provide an easier way.
