I already been posted this in response to someone else, but it may not
be obvious to users of this problem.
nfs-utils-lib-1.1.4-6.fc11.i586
nfs-utils-1.2.0-3.fc11.i586
Basically the latest nfs update disables NFS4, the server log file shows
something like:
Jul 18 10:47:10 username kernel: svc: 192.168.10.100, port=897: unknown
version (4 for prog 100003, nfsd)
On the client, the message will be something like:
mount.nfs4: Protocol not supported
rpcinfo -p (on the server) will not show any version 4 protocols.
The short term fix is:
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)
