- Seal the KMS such that it cannot be accessed by MinIO server anymore. That will lock **all** SSE-S3 encrypted objects protected by master keys stored on the KMS. All these objects can not be decrypted as long as the KMS is sealed.
- Seal/Unmount one/some master keys. That will lock all SSE-S3 encrypted objects protected by these master keys. All these objects can not be decrypted as long as the key(s) are sealed.

* A new volume manager was introduced in kubelet that synchronizes volume mount/unmount (and attach/detach, if attach/detach controller is not enabled). ([#26801](https://github.com/kubernetes/kubernetes/pull/26801), [@saad-ali](https://github.com/saad-ali))
    * This eliminates the race conditions between the pod creation loop and the orphaned volumes loops. It also removes the unmount/detach from the `syncPod()` path so volume clean up never blocks the `syncPod` loop.

* Fix issue when attempting to unmount a wrong vSphere volume ([#37413](https://github.com/kubernetes/kubernetes/pull/37413), [@BaluDontu](https://github.com/BaluDontu))

#### Other Notable Changes
* Implement bulk polling of volumes ([#41306](https://github.com/kubernetes/kubernetes/pull/41306), [@gnufied](https://github.com/gnufied))

- Fixed smb remount and unmount issues on Windows ([#73661](https://github.com/kubernetes/kubernetes/pull/73661), [@andyzhangx](https://github.com/andyzhangx), [#75087](https://github.com/kubernetes/kubernetes/pull/75087), [@andyzhangx](https://github.com/andyzhangx))

- Fix: azure file mount timeout issue ([#88610](https://github.com/kubernetes/kubernetes/pull/88610), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Fix: corrupted mount point in csi driver ([#88569](https://github.com/kubernetes/kubernetes/pull/88569), [@andyzhangx](https://github.com/andyzhangx)) [SIG Storage]

- On compatible systems, a mounter's Unmount implementation is changed to not return an error when the specified target can be detected as not a mount point. On Linux, the behavior of detecting a mount point depends on `umount` command is validated when the mounter is created. Additionally, mount point checks will be skipped in CleanupMountPoint/CleanupMountWithForce if the mounter's Unmount having the changed behavior of not returning error when target is not a...

### Non-recursive Volume Ownership (FSGroup) graduates to Beta

By default, the `fsgroup` setting, if specified, recursively updates permissions for every file in a volume on every mount. This can make mount, and pod startup, very slow if the volume has many files. 

* Fix stackdriver metrics for node memory using wrong metric type ([#63535](https://github.co/kubernetes/kubernetes/pull/63535), [@serathius](https://github.com/serathius))
* fix mount unmount failure for a Windows pod ([#63272](https://github.com/kubernetes/kubernetes/pull/63272), [@andyzhangx](https://github.com/andyzhangx))
