This is verified on 
oc v3.11.66
kubernetes v1.11.0+d4cacc0
features: Basic-Auth GSSAPI Kerberos SPNEGO

Server https://ip-172-18-12-68.ec2.internal:8443

1.Create two nfs recyled pv
[root@ip-172-18-12-68 ~]# oc get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                  STORAGECLASS   REASON    AGE
nfs-1                                      5Gi        RWX            Recycle          Available                                                   2m
nfs-2                                      5Gi        RWX            Recycle          Available                                                          
2.Create a pvc nfsc-1, and bound to one pv nfs-1
[root@ip-172-18-12-68 ~]# oc get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                  STORAGECLASS   REASON    AGE
nfs-1                                      5Gi        RWX            Recycle          Bound       s4l93/nfsc-1                                    9m
nfs-2                                      5Gi        RWX            Recycle          Available                                                   10m
3.Create pod nfs-1, using pvc nfsc-1

4.Prepare the pvc yaml file, make the pvc nfs-1 bound to pv nfs-2
{
    "apiVersion": "v1",
    "kind": "PersistentVolumeClaim",
    "metadata": {
        "name": "nfsc-1"
    },
    "spec": {
        "volumeName": "nfs-2",
        "accessModes": [ "ReadWriteMany" ],
        "resources": {
            "requests": {
                "storage": "5Gi"
            }
        }
    }
}
~   
5.Re-create pvc nfsc-1
[root@ip-172-18-12-68 ~]# ./test.sh 
pod "nfs-1" deleted
persistentvolumeclaim "nfsc-1" deleted
persistentvolumeclaim/nfsc-1 created
pod/nfs-1 created
6.Check pv status
[root@ip-172-18-12-68 ~]# oc get pv
NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                  STORAGECLASS   REASON    AGE
nfs-1                                      5Gi        RWX            Recycle          Available                                                   12m
nfs-2                                      5Gi        RWX            Recycle          Bound       s4l93/nfsc-1
