Once CSI migration is enabled for vSphere, the following tests are consistently failing:
[sig-storage] In-tree Volumes [Driver: vsphere] [Testpattern: Inline-volume (ext4)] volumes should store data [Suite:openshift/conformance/parallel] [Suite:k8s]
[sig-storage] In-tree Volumes [Driver: vsphere] [Testpattern: Inline-volume (default fs)] volumes should store data [Suite:openshift/conformance/parallel]
According to this documentation , inline volumes in the pod spec is NOT supported by the vSphere CSI driver.
This could explain why these tests are failing. I asked VMware folks upstream in this  Slack thread, but I haven't received any answer yet.
