So I tried to use the default NFS settings, with no luck.
Then I upgraded to 3.3.1, still with no luck.

Seems like the NFS connection is unable to perform a failover. I would 
really love to hear if someone have this working.

The reason I want this is to use glusterfs to store virtual machines 
for VMware.
