Description Jan Safranek 2021-08-05 17:18:11 UTC

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
