Description of problem: Azure Stack Hub does not support in-tree volume plugin for azure disk. We do not even create a StorageClass for it during installation. Only the CSI driver is supported there, however, the driver is not installed by default. Version-Release number of selected component (if applicable): 4.9.0-0.ci-2021-08-05-062416 How reproducible: Always Steps to Reproduce: 1. Install OCP on Azure Shack Hub Actual results: No default storage class exists No CSI driver is installed Expected results: AzureDisk CSI driver is installed with a default storage class. As workaround, users can enable TechPreviewNoUpgrade feature set. It has a few downsides: * The cluster is not upgradeable to 4.10. * All nodes are drained during the process (i.e. it takes quite some time for the cluster to stabilize). oc patch featuregate cluster -p "{\"spec\":{\"featureSet\": \"TechPreviewNoUpgrade\"}}" --type=merge -o yaml
