And then restart the server.
After doing the mount from the client, check the journal for rpc.mountd
messages.
Ok, what I got when doing 'mount -v server:/path /path' (i.e. it tried
v4 first then succeeded on v3) was
rpc.mountd[20558]: check_default: access by 192.168.1.103 ALLOWED

That is the output I get when I disable NFSv4 in /etc/nfs.conf.
The other way to disable NFSv4 is to modify /etc/sysconfig/nfs to have the line
# Optional arguments passed to rpc.nfsd. See rpc.nfsd(8)
RPCNFSDARGS="--no-nfs-version 4"
You should check that as well.
Bottom line, NFSv4 is set disabled. Those are the 2 ways I know how to do.
Maybe there
are more?
Could it be that v4 differs from v3 in how it does IP <-> hostname
resolution? On the server I have the IP of the client/desktop in the
/etc/hosts file and the /etc/exports has only the hostname
No. You see "access by 192.168.1.103 ALLOWE" in all attempts.
