I believe the LVMCLuster examples need to specify the openshift-storage namespace, otherwise I get this error:

"error":"cross-namespace owner references are disallowed, owner's namespace <ns>, obj's namespace openshift-storage"

4.15 & older  

  When namespace is not defined, no topolvm pods are created

    1. Copy LVMCLuster example from docs & apply
    2. Nothing happens
    3.
    

    No topolvm pod creation

Example copied from doc should define all params needed    

    Adding the namespace succeeds:

kind: LVMCluster
metadata:
  name: my-lvmcluster
  namespace: openshift-storage
