Doc Type: Enhancement
Doc Text:
Feature: Enable users to specify mount options with Persistent Volumes (including NFS and other volume types that support it). See openshift document for more information. Reason: Occasionally default mount options used by Openshift is not good enough for NFS and other volume types. This feature allows users to tweak mount options depending on their storage configuration. Result: Implemented support for mount options in NFS and other volume types that support it.

  accessModes:
     - ReadWriteOnce
  nfs:
