Clone a FlashArray PersistentVolumeClaim

Cloning a PersistentVolumeClaim (PVC) creates a new volume that duplicates the data in the original PVC. This can be useful for testing, development, or backup scenarios where you need a safe copy of the volume.

note

FlashArray file services and FlashBlade file systems do not support PVC cloning.

1. Create the clone PVC definition:

   Define a new PVC with a dataSource referencing the name of the source PVC:

   apiVersion: v1
   kind: PersistentVolumeClaim
   metadata:
     name: pvc-clone
   spec:
     accessModes: # accesMode must be same as the parent PVC
       - ReadWriteOnce
     resources:
       requests:
         storage: 20Gi # storage size must be same as the parent PVC
     storageClassName: sc-portworx-fa-direct-access
     dataSource:
       kind: PersistentVolumeClaim
       name: pure-claim-block

2. Apply the manifest:

   Save the configuration to a file named clone.yaml and apply it:

   kubectl apply -f clone.yaml

   persistentvolumeclaim/pvc-clone created

3. Verify the cloned PVC:

   Confirm that the new PVC has been created:

   kubectl get pvc <pvc-clone> -n <pvc-namespace>
