      * Previously, the Manila Container Storage Interface (CSI) driver had services running on unintended hosts. This occurred because the Manila CSI driver uses a single binary for both the controller and node (worker) services. With this release, the CSI driver controller pods run only controller services, and CSI driver node pods run only node services. (https://issues.redhat.com/browse/OCPBUGS-54447[OCPBUGS-54447])

      Both the Cinder and Manila CSI drivers use a single binary for both the controller and node (worker) services. This means we can end up with services running on hosts where they shouldn't be run. We fixed this in Cinder in 4.18 [1]. We should now do the same for Manila.
