+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 
+server
+
+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.
