Volume Resizing

This example shows how to resize BSU persistence volume using volume resizing features.

Note

  • BSU has a limitation with volume modification only when state is available. Refer to API documentation for more details.

Usage

  1. Add allowVolumeExpansion: true in the StorageClass spec in example manifest to enable volume expansion. You can only expand a PVC if its storage class’s allowVolumeExpansion field is set to true

  2. Deploy the example:

kubectl apply -f specs/
  1. Verify the volume is created:
kubectl get pv
  1. Expand the volume size by increasing the capacity in PVC's spec.resources.requests.storage:
 kubectl edit pvc -n resizing-p bsu-claim

Save the result at the end of the edit.

  1. Verify that the persistence volume are resized:
kubectl get pv

You should see the new value relfected in the capacity fields.

  1. Cleanup resources:
kubectl delete -f specs/
