    • The Cluster Storage Operator and vSphere CSI driver operator use correct labels that restrict them to be scheduled only on on CPUs assigned to run control plane workloads in environments that are configured with CPU workload pinning enabled.

      This is a clone of issue OCPBUGS-8683. The following is the description of the original issue:
      —
      Clone of OCPBUGS-7906, but for all the other CSI drivers and operators than shared resource. All Pods / containers that are part of the OCP platform should run on dedicated "management" CPUs (if configured). I.e. they should have annotation 'target.workload.openshift.io/management:{"effect": "PreferredDuringScheduling"}' .

      Enhancement: https://github.com/openshift/enhancements/blob/master/enhancements/workload-partitioning/management-workload-partitioning.md

      So far nobody ran our cloud CSI drivers with CPU pinning enabled, so this bug is a low prio. I checked LSO, it already has correct CPU pinning in all Pods, e.g. here.
