if you want to allow root to perform rw on nfs then use
(no_root_squash,rw,sync)

1). are you able to ping nfs server (to-from)?
2). check /etc/hosts file.
3). check firewall
4). check SELinux.

if that didn't worked, send.
a) your hosts file
b) logs of the duration when you restart your nfs service from
terminal. (/var/log/messages)
c) logs when you try to mount nfs share on client. (/var/log/messages)
