Creating volume clones

The cloning feature enables you to specify an existing PVC as a dataSource while creating a new PVC. Prerequisites are as under:

  • The source PVC is bound and available for use

  • A valid Storage Class is available

  • The source PVC is created using the InfoScale CSI driver that supports volume cloning

To clone a PVC from an existing PVC:

  1. Identify the PVC that you want to clone. 
     oc get pvc
  2. Define the PersistentVolumeClaim object using the yaml and specify the name of the PVC object to use as source
    csi-dynamic-volume-clone.yaml
---
  kind: PersistentVolumeClaim
  apiVersion: v1
  metadata:
    name: csi-infoscale-volume-clone
  spec:
    storageClassName: csi-infoscale-sc
    accessModes:
      - ReadWriteMany
    resources:
      requests:
        storage: 5Gi
    dataSource:
      kind: PersistentVolumeClaim
      name: csi-infoscale-pvc
  3. Create a volume clone
     oc create -f csi-dynamic-volume-clone.yaml

    On successful creation of a clone, it is pre-populated with the data from the specified PVC dataSource volume.
