Notes:
- vSphere CSI driver is not supported on Windows based vCenter.
- Native K8s is any distribution that uses vanilla upstream Kubernetes binaries and pods (e.g. VMware TKG, TKGI, etc)
- If the CSI version
2.0driver is installed on K8s running on vSphere 6.7U3, the older CSI1.0driver features continue to work but the new CSI2.0features are not supported. - If the CSI version
1.0.2is installed on K8s running on vSphere 7.0, the CSI1.0driver features continue to work. CSI version1.0.1is not compatible with vSphere 7. - CSI version
1.0.xand CSI version2.0on vSphere 6.7U3, vSphere with K8s, TKG ‘Guest’ and PKS 1.7 only support dynamically provisioned block (RWO) volumes on vSphere storage. - The dynamic creation of read-write-many (
RWX) and read-only-many (ROX) file based Persistent Volumes is only available in vSphere 7.0 through vSAN 7.0 File Services. - PV Encryption, offline volume grow and Topology/AZ support are only available on block based Persistent Volumes. These features are not available with PVs backed by file shares.
- Offline volume expansion requires a minimum Kubernetes version of 1.16+, and is also a beta feature in this release. This feature is enabled by default in vSphere 7.0 for Native K8s and in vSphere 7.0U1 for TKG clusters.
- Multi-node Control Planes only supports having a single CSI Pod being active at any time (replica = 1 in controller manifest).
WaitForFirstConsumeris a K8s feature that delays volume binding until the Pod has been scheduled, and is used for Pod and PV placement.- Volume health is supported for block volumes in vSphere with Kubernetes Cluster and Tanzu Kubernetes Grid Cluster - vSphere 7.0u1.
