I have 2 different namespace: prod-01 and prod-02, What I want to do is build a copy of my prod-01 into prod-02 namespace keeping the same names for its pvcs, so that I don't have to maintain 2 sets of charts for each different namespace.

Here's how it looks like:

$ kubectl get ns | grep prod
prod-01          Active    178d
prod-02          Active    8d
$ 

As shown below, I have 2 pairs of pv's for each namespace:

$ kubectl get pv -o wide | grep prod
prod-01-db-pv                    50Gi       RWX            Retain           Bound       prod-01/app-db                                                                      164d
prod-01-nosql-db-pv              5Gi        RWX            Retain           Bound       prod-01/app-nosql-db                                                                149d
prod-02-db-pv                50Gi       RWX            Retain           Available   prod-02/app-db                                                          41m
prod-02-nosql-db-pv          5Gi        RWX            Retain           Available   prod-02/app-nosql-db                                                    19m
$ 

Here's how pvc's for prod-01 are being displayed:

$ kubectl get pvc --namespace=prod-01
NAME              STATUS    VOLUME               CAPACITY   ACCESS MODES   STORAGECLASS   AGE
app-db         Bound     prod-01-db-pv         50Gi       RWX                           164d
app-nosql-db   Bound     prod-01-nosql-db-pv   5Gi        RWX                           149d
$ 

And here's what I'm trying to accomplish:

$ kubectl get pvc --namespace=prod-02
NAME              STATUS    VOLUME                   CAPACITY   ACCESS MODES   STORAGECLASS   AGE
app-db         Pending   prod-02-db-pv         0                                        2m
app-nosql-db   Pending   prod-02-nosql-db-pv   0                                        24m
$ 

As shown above, the pvc's for prod-02 namespace are stuck forever with Pending status.

Them when I change the pvc names on prod-02 to anything different, they bond as expected.

Which leads me to think I can't use the same names on pvc's even when they are in different namespaces and pointing to different pv's ... However, when searching the documentation, I could not find any evidence to this issue, and was wondering if I could be missing something.

So to put it simple, can I have multiple pvc's with the same name accross different namespaces (considering that they are using different pv's)?

Update: result of kubectl describe pvc

$ kubectl describe pvc app-db --namespace=prod-02
Name:          app-db
Namespace:     prod-02
StorageClass:  
Status:        Pending
Volume:        prod-02-db-pv

Annotations:   <none>
Finalizers:    []
Capacity:      0
Access Modes:  
Events:        <none>
$ 

Also here's the output of kubectl get pvc:

$ kubectl get pvc app-db --namespace=prod-02  -o yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  creationTimestamp: 2018-09-22T22:00:34Z

  - ReadWriteMany
  resources:
    requests:
      storage: 50Gi
  volumeName: prod-02-db-pv

$ 

And here are some details about the pv too:

$ kubectl get pv prod-02-db-pv --namespace=prod-02 -o yaml
apiVersion: v1
kind: PersistentVolume
metadata:
  creationTimestamp: 2018-09-22T21:15:19Z

$ 

Thanks in advance for the help!
