Ouch... You're running an obsolete alternative nfs server. You should 
uninstall the unfs3 package, and this package should get removed from 
the distribution.

To summarize, here are the mandatory steps:
- check you have nfs-utils-clients installed on clients
- check you have nfs-utils-clients and nfs-utils installed on server
- check rpcbind, and nfs-common services are running on clients
- check rpcbind, nfs-common and nfs-server services are running on the 

Once done, check with rpcinfo -s <address> what is actually running on 
each host.

Now, to ensure usage of NFSv4 instead of obsolete NFSv3:
- check every host is configured to run rpc.idmapd, meaning 
NEED_IDMAPD=yes in /etc/sysconfig/nfs-common
- check your server export a root filesystem, using fsid=0 options in 
its /etc/exports configuration file
- drop all your legacy nfs options, such as wsize and rsize from your 
mount options

Last, you'd better use autofs to mount those filesystems on demand, 
rather than hardcoding them in /etc/fstab, which avoid to relies on 
server availability during the boot.

BOFH excuse #408:

Computers under water due to SYN flooding.
