title: rancher - help on getting NFS working - volumeDriver.create: failed
body: <p>I've installed NFS 0.30 (last version) stack using catalog.
  The options are:</p>
  
  <pre><code>MOUNT_DIR   / 
  MOUNT_OPTS    proto=tcp,port=2049,nfsvers=4 
  NFS_SERVER    xxx.xxx.xxx.xxx (digitalocean droplet public ip)
  </code></pre>
  
  <p>The container starts normally and seems to be working fine. So, then I try to create a simple stack using the NFS with this docker-compose:</p>
  
  <pre><code>version: '2'
  services:
    web:
      image: nginx
      volumes:
      - bar:/var/bar
  
  volumes:
    bar:
      driver: rancher-nfs
  </code></pre>
  
  <p>And I get this error:</p>
  
  <p><code>(Expected state running but got error: Error response from daemon: create aaaa_bar_8fa9a: VolumeDriver.Create: Failed nsenter -t 11437 -n mount -o proto=tcp,port=2049,nfsvers=4 xx.xx.xx.xx:/ /tmp/5ht8d)</code></p>
