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/

3. Verify the volume is created:

kubectl get pv 

4. 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.

5. Verify that the persistence volume are resized:

kubectl get pv

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

7. Cleanup resources:

kubectl delete -f specs/
