   A *PersistentVolume* is a specific resource.  A *PersistentVolumeClaim* is a request for a resource with specific attributes, such as storage size.
   In between the two is a process that matches a claim to an available volume and binds them together.  This allows the claim to be used
  -  as a volume in a pod.  OpenShift finds the volume backing the claim and mounts it into the pod.

   You can tell whether a claim or volume is bound by querying the CLI:

  Storage is provisioned by an administrator by creating *PersistentVolume* objects from sources such as GCE Persistent Disks,
  AWS Elastic Block Stores, and NFS mounts

negative.code: == Overview
  
  A *PersistentVolume* object is a storage resource in an OpenShift cluster.  It is provisioned by an administrator
  and made available to users who lay claims to the resource.
  
  A *PersistentVolumeClaim* object is a request for storage resources by a pod author.  The claim is paired with a
  volume that generally matches the user's request.
