The thing with this way of failover is though, that you will likely corrupt a
currently written file. If your NFS-server (gluster) node dies while you write
your file will be corrupt. If you use native glusterfs mounts it will not
(should not). This is why I consider the NFS server feature nothing more than
a bad hack. It does not deliver the safety that glusterfs promises, even if
you solve the failover problem somehow.
