The issue is we need:

oc adm policy add-scc-to-user hostmount-anyuid -z openebs-lvm-node-sa -n openebs

or

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding

  - kind: ServiceAccount
    name: openebs-lvm-node-sa

From the log snippet it appears provision request hasn't even come to lvm provisioner. Could you share the storage class definition please?

See the solution I provided. helm chart need to incorporate that.
