## Known Issues

* kubeadm now detects the Docker cgroup driver and starts the kubelet with the matching driver. This eliminates a common error experienced by new users in when the Docker cgroup driver is not the same as the one set for the kubelet due to different Linux distributions setting different cgroup drivers for Docker, making it hard to start the kubelet properly.

feature gate is enabled, user should not upgrade to Kubernetes v1.22. vSphere CSI Driver does not support Kubernetes v1.22 yet because it uses v1beta1 CRD APIs. Support for v1.22 will be added at a later release. Check the following document for supported Kubernetes releases for a given [vSphere CSI Driver version](https://vsphere-csi-driver.sigs.k8s.io/compatiblity_matrix.html#compatibility-matrix-for-vsphere-csi-driver).

### Workloads that saturate nodes with pods may see pods that fail...

- This release enables in-tree RBD migration to CSI driver with a couple of feature gates.  These featuregates are alpha in this release.

  - `CSIMigrationRBD`: when enabled, it will redirect traffic from in tree rbd plugin ( kubernetes.io/rbd )  to CSI driver ( rbd.csi.ceph.com) , default to `false` now.
  - `IntreePluginRBDUnregister`: Disables the RBD in-tree driver

  The feature gates can be enabled by:

- Set CSIMigrationvSphere feature gates to beta.
  Users should enable CSIMigration + CSIMigrationvSphere features and install the vSphere CSI Driver (https://github.com/kubernetes-sigs/vsphere-csi-driver) to move workload from the in-tree vSphere plugin "kubernetes.io/vsphere-volume" to vSphere CSI Driver.
  

#### Storage

  General Support for vSphere 6.7 will end on October 15, 2022. vSphere 6.7 Update 3 is deprecated in Kubernetes v1.24.  Customers are recommended to upgrade vSphere (both ESXi and vCenter) to 7.0u2 or above.  vSphere CSI Driver 2.2.3 and higher supports CSI Migration.
