Directly editing the size of a PersistentVolume can prevent an automatic resize of that volume.
If you edit the capacity of a PersistentVolume, and then edit the `.spec` of a matching
PersistentVolumeClaim to make the size of the PersistentVolumeClaim match the PersistentVolume,
then no storage resize happens.
The Kubernetes control plane will see that the desired state of both resources matches,
conclude that the backing volume size has been manually
increased and that no resize is necessary.
