And the changes are replicated back when the failed node reappears. If you mount it via glusterfs, the hostname is only used during mount to fetch the meta-data. With nfs-mount the mount only runs on when the mounted node runs. Of course trying to use a shut-down node doesn't work on either nfs nor glusterfs...
