If you are interested there are HA solutions available with NFS. It 
depends on NFS solution which u are trying, if it is gluster 
nfs(integrated nfs server with gluster) then use ctdb and for 
NFS-Ganesha , we already have an integrated solution with pacemaker/corosync

Please update ur gluster version since it EOLed, you don't receive any 
more update for that version.
