   == Provisioning
   
  -Storage must exist in the underlying infrastructure before it can be mounted as
  -a volume in OpenShift. To provision Ceph volumes in OpenShift, the following
  -information is required:
  -
  -- The ceph key to be used in an OpenShift secret object.
  -- The ceph image name.
  +To provision Ceph volumes, the following are required:
  +
  +- An existing storage device in your underlying infrastructure.
  +- The Ceph key to be used in an {product-title} secret object.
  +- The Ceph image name.
   - The file system type on top of the block storage (e.g., ext4).
  -
  -You must also ensure that the *ceph-common* package is installed on *_all_*
  -schedulable OpenShift nodes:
  -
  +- *ceph-common* installed on each schedulable {product-title} node in your cluster:
  ++
   ----
   # yum install ceph-common
   ----
  
positive.code:       storage: 2Gi <2>
  
  ----
  <1> As mentioned above for PVs, the `*accessModes*` do not enforce access right,
  but rather act as labels to match a PV to a PVC.
  <2> This claim will look for PVs offering *2Gi* or greater capacity.
  ====
  
  Save the definition to a file, for example *_ceph-claim.yaml_*, and create the
  PVC:
  
  ====
  ----
  # oc create -f ceph-claim.yaml
