Description of problem:
The status of the persistent volume claims and the persistent volumes don’t fit together.Persistent Volumes are marked in the state of released, but are still in use and bound in an persistent volume claim.

How reproducible:


Steps to Reproduce:
1. Create pv 

cat pv1.json
{
  "apiVersion": "v1",
  "kind": "PersistentVolume",
  "metadata": {
    "name": "pv0001"
  },
  "spec": {
    "capacity": {
        "storage": "1Gi"
    },
    "accessModes": [ "ReadWriteOnce" ],
    "nfs": {
        "path": "/home/data/pv0001",
        "server": "10.65.x.y"
    },
    "persistentVolumeReclaimPolicy": "Recycle"
  }
}

oc create -f pv1.json

- Claim pv.

cat pvc.json
{
    "apiVersion": "v1",
    "kind": "PersistentVolumeClaim",
    "metadata": {
        "name": "claim1"
    },
    "spec": {
        "accessModes": [ "ReadWriteOnce" ],
        "resources": {
            "requests": {
                "storage": "1Gi"
            }
        }
    }
}

oc create -f pvc.json

[chris@master1 ~]$ oc get pv
NAME      LABELS    CAPACITY   ACCESSMODES   STATUS    CLAIM            REASON    AGE
pv0001    <none>    1Gi        RWO           Bound     persist/claim1             57m
[chris@master1 ~]$ oc get pvc
NAME      LABELS    STATUS    VOLUME    CAPACITY   ACCESSMODES   AGE
claim1    <none>    Bound     pv0001    1Gi        RWO           57m

3) Delete the claim :

oc delete pvc claim1
persistentvolumeclaim "claim1" deleted

oc get pv
NAME      LABELS    CAPACITY   ACCESSMODES   STATUS     CLAIM            REASON    AGE
pv0001    <none>    1Gi        RWO           Released   persist/claim1             57m

4) Now create the persistent volume claim again:

oc create -f pvc.json
persistentvolumeclaim "claim1" created


5) See the status of pv and pvc where pvc shows bound status with pv0001 while pv0001 shows released state :

oc get pvc
NAME      LABELS    STATUS    VOLUME    CAPACITY   ACCESSMODES   AGE
claim1    <none>    Bound     pv0001    1Gi        RWO           4s
[chris@master1 ~]$ oc get pv
NAME      LABELS    CAPACITY   ACCESSMODES   STATUS     CLAIM            REASON    AGE
pv0001    <none>    1Gi        RWO           Released   persist/claim1             58m


Actual results: It is showing inconsistent state.


Expected results: It should have shown consistent state for pv and pvc both i.e bound state.


Additional info: The issue is only namespace/name was used for binding
PVCs instead of using the object UID to guarantee it is a different
object. Below is the upstream link with fix.
