 new PersistentVolume is never created to satisfy the claim. Instead, an existing volume is resized.

+Editing the size of a PersistentVolume can prevent resize of the volume. If the
+capacity of a PersistentVolume edited, then the PersistentVolumeClaim size is edited to increase to
+the same value, no resize will happen. Kubernetes will think the backing volume has been manually
+increased and that no resize is necessary.
