Manual steps

In certain scenarios, manual steps are required.

Persistent storage for StatefulSet is full

1. Set spec.allowVolumeExpansion: true in the gp3 (default) storageclass on aws.
2. Manually set the persistentVolumeClaims corresponding to the statefulset to the new desired size
3. Do not modify the art.yaml file or the statefulset config itself used to create the application as that would result in an error. This is because of this upstream issue in kubernetes
