Volume cloning enables users to specify another PVC as a "DataSource" when provisioning a new volume. If the underlying storage system supports this functionality and implements the "CLONE_VOLUME" capability in its CSI driver, then the new volume becomes a clone of the source volume.

## Changelog since v1.26.2

## Changes by Kind

### API Change

- Volumes: `resource.claims` gets cleared for PVC specs during create or update of a pod spec with inline PVC template or of a PVC because it has no effect. ([#115928](https://github.com/kubernetes/kubernetes/pull/115928), [@pohly](https://github.com/pohly)) [SIG API Machinery, Apps and Storage]

### Feature

* You can now change the size of an azuredisk PVC using `kubectl edit pvc pvc-azuredisk`. Note that this operation will fail if the volume is already attached to a  running VM. ([#64386](https://github.com/kubernetes/kubernetes/pull/64386), [@andyzhangx](https://github.com/andyzhangx))

  CSIMigrationAzureFile features and install the [AzureFile CSI Driver](https://github.com/kubernetes-sigs/azurefile-csi-driver)
  to avoid disruption to existing Pod and PVC objects at that time. Azure File CSI driver does not support using same persistent
  volume with different fsgroups. When CSI migration is enabled for azurefile driver, such case is not supported.

- Display Labels when kubectl describe ingress. ([#103894](https://github.com/kubernetes/kubernetes/pull/103894), [@kabab](https://github.com/kabab))
- Enhance scheduler `VolumeBinding` plugin to handle Lost PVC as `UnschedulableAndUnresolvable` ([#105245](https://github.com/kubernetes/kubernetes/pull/105245), [@yibozhuang](https://github.com/yibozhuang))

- Add `DataSourceRef` alpha field to PVC spec, which allows contents other than `PVCs` and `VolumeSnapshots` to be data sources. ([#103276](https://github.com/kubernetes/kubernetes/pull/103276), [@bswartz](https://github.com/bswartz))

- Fix kubelet restart unmounts volumes of running pods if the referenced PVC is being deleted by the user ([#130686](https://github.com/kubernetes/kubernetes/pull/130686), [@carlory](https://github.com/carlory)) [SIG Node, Storage and Testing]

- In some cases, a Flex volume resize may leave a PVC with erroneous Resizing condition even after volume has been successfully expanded. Users may choose to delete the condition, but it is not required. ([#71470](https://github.com/kubernetes/kubernetes/issues/71470))

* Fix leaking ingress resources in federated ingress e2e test. ([#34652](https://github.com/kubernetes/kubernetes/pull/34652), [@quinton-hoole](https://github.com/quinton-hoole))
* pvc.Spec.Resources.Requests min and max can be enforced with a LimitRange of type "PersistentVolumeClaim" in the namespace ([#30145](https://github.com/kubernetes/kubernetes/pull/30145), [@markturansky](https://github.com/markturansky))

* Implement dry run support in kubefed init ([#36447](https://github.com/kubernetes/kubernetes/pull/36447), [@irfanurrehman](https://github.com/irfanurrehman))
* Make federation etcd PVC size configurable ([#36310](https://github.com/kubernetes/kubernetes/pull/36310), [@irfanurrehman](https://github.com/irfanurrehman))
