Have you considered an NFS cluster based on pacemaker/openais/corosync?
See <http://www.clusterlabs.org/>. One possible config is an active/passive
cluster using NFS on top of DRBD. I've never clustered samba, but it
looks like others have done it:

Google will show you various problems with active/active clusters related to
both GFS2 and samba. Don't try to have your NFS servers also be NFS
clients.
For reasonable security/authentication, you'd probably want to integrate
with kerberos.
