Re: RHEL 5 & NFS Input/Output Error

This message usually means that NFS server and client do not agree on the version of NFS offered, however this might not be the cause of your problems.

So, could you login as root to the RHEL3 boxes and do an:

rpcinfo -p server (server=resolvable name of your RHEL5).

and provide the output?

Also, what are the mount options you use on the /etc/fstab file (or automount config) on the RHEL3 side to mount the home dirs from RHEL5? Do the NFS imported partitions show up in df, does it hang, display the partitions as mounted but with no util info?...

Interstingly enough, I'm seeing the same thing - I have a RHEL 5 NFS server running and a bunch of RHEL 3 workstations mounting user home directories from the RHEL 5 server.

I can ssh into the workstations but creating files gives the same Input/Output error. The server hard drives are fine BUT I do see this in /var/log/messages on every occurrence on the clients:

kernel: svc: unknown version (3)

I'm not able to log into the clients from the GUI so something serious is going on.
