Thanx Dan,

I have done that, but it seems that either these settings don't work on CentOS5.4, or I'm doing something wrong.

root@mars:[~]$ mount.nfs4  master1.mydomain.co.za:/ /bck
mount.nfs4: Protocol not supported


I did some google search on this, and apparently I need to change some settings in /etc/init.d/nfs on like 97, but my /etc/init.d/nfs looks different from those in the search results. So, I guess the search results are related to older versions?

Here's a snippet from a google search:

edit your "/etc/init.d/nfs" file as follows:

Comment out line 97 and add the following line (which removes the -N 4.1)



        echo -n $"Starting NFS daemon: "
        # For now, turn off the nfs41 support
#       daemon rpc.nfsd -N 4.1 $RPCNFSDARGS $RPCNFSDCOUNT
        daemon rpc.nfsd $RPCNFSDARGS $RPCNFSDCOUNT



Then, restart your NFS server (service nfs restart)

It should then work (mine does)

This one site (http://www.citi.umich.edu/projects/nfsv4/linux/using-nfsv4.html) though had a walkthrough, but I still don't get it to work.

Any suggestions?
