// Design:
//
// The fundamental key to this design is the bi-directional "pointer" between
// PersistentVolumes (PVs) and PersistentVolumeClaims (PVCs), which is
// represented here as pvc.Spec.VolumeName and pv.Spec.ClaimRef. The bi-
// directionality is complicated to manage in a transactionless system, but

- Added scheduler preemption support for pods using `ReadWriteOncePod` PVCs ([#114051](https://github.com/kubernetes/kubernetes/pull/114051), [@chrishenzie](https://github.com/chrishenzie))

	om.podsIndexer.Update(pods[0])
	if _, err := ssc.UpdateStatefulSet(context.TODO(), set, pods); err != nil {
		t.Errorf("Error updating StatefulSet %s", err)
	}
	// invariants check if there any missing PVCs for the Pods
	if err := invariants(set, om); err != nil {
		t.Error(err)
	}
	_, err = om.podsLister.Pods(set.Namespace).List(selector)
	if err != nil {
		t.Error(err)
	}
}

## Changelog since v1.8.10

### Action Required

* ACTION REQUIRED: In-place node upgrades to this release from versions 1.7.14, 1.8.9, and 1.9.4 are not supported if using subpath volumes with PVCs.  Such pods should be drained from the node first. ([#61373](https://github.com/kubernetes/kubernetes/pull/61373), [@msau42](https://github.com/msau42))
