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