title: Kubernetes NFS Mount Options
body: <p>I've recently started using NFS volumes for my clusters on-prem. This is the simplest and best solution for me, however it seems pretty limited in regards to the actual mounts options.</p>
  
  <p>Is there anyway to set mount options on the node/cluster in the volume.yml files?</p>
  
  <ul>
  <li>NFSv3</li>
  <li>NFSv4/4.1</li>
  <li>lookupcache</li>
  <li>noatime</li>
  <li>rsize,wsize</li>
  </ul>
  
  <p>I have application that requires a specific version and also these mount options for performance.</p>
  
  <pre><code>apiVersion: v1
  kind: PersistentVolume
  metadata:
    name: nfs
  spec:
    capacity:
      storage: 1Mi
    accessModes:
      - ReadWriteMany
    nfs:
      # FIXME: use the right IP
      server: 10.244.1.4
      path: "/"
  </code></pre>
  
  <p>Is there anyway to add mount flags here?</p>
