### CSI Health Monitoring

The CSI health monitoring feature is being released as a second Alpha in Kubernetes 1.21. This feature enables CSI Drivers to share abnormal volume conditions from the underlying storage systems with Kubernetes so that they can be reported as events on PVCs or Pods. This feature serves as a stepping stone towards programmatic detection and resolution of individual volume health issues by Kubernetes.

## Known Issues

  See https://github.com/kubernetes/kubernetes/issues/102750. ([#103231](https://github.com/kubernetes/kubernetes/pull/103231), [@n4j](https://github.com/n4j))
- Fixed applying of SELinux labels to CSI volumes on very busy systems (with "error checking for SELinux support: could not get consistent content of /proc/self/mountinfo after 3 attempts") ([#105934](https://github.com/kubernetes/kubernetes/pull/105934), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]

<p>
Go is a general-purpose language designed with systems programming
in mind. It is strongly typed and garbage-collected and has explicit
support for concurrent programming.  Programs are constructed from
<i>packages</i>, whose properties allow efficient management of
dependencies.

With CSI the Kubernetes volume layer becomes truly extensible, allowing third party storage developers to write drivers making their storage systems available in Kubernetes without having to touch the core code.

CSI was first introduction as alpha in Kubernetes v1.9 and moved to beta in Kubernetes v1.10.

* Fix kube-controller-manager panic while provisioning Azure security group rules ([#64739](https://github.com/kubernetes/kubernetes/pull/64739), [@feiskyer](https://github.com/feiskyer))
* Fixes issue for readOnly subpath mounts for SELinux systems and when the volume mountPath already existed in the container image. ([#64351](https://github.com/kubernetes/kubernetes/pull/64351), [@msau42](https://github.com/msau42))

- Fixed using volume partitions on AWS Nitro systems. ([#100500](https://github.com/kubernetes/kubernetes/pull/100500), [@jsafrane](https://github.com/jsafrane)) [SIG Storage]

- Fixed a bug where containers would not start on cgroupv2 systems where swap is disabled. ([#120924](https://github.com/kubernetes/kubernetes/pull/120924), [@klueska](https://github.com/klueska)) [SIG Node]
- Fixed a regression in kube-proxy where it might refuse to start if given

- 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....
