    • 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.

    Description

      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.

          Bug - A problem that impairs or prevents the functions of the product. OCPBUGS-8683 CSI driver + operator containers are not pinned to mgmt cores

          • Normal - To be worked after urgent and high priorities are resolved. This term is chosen when the severity of an issue is relatively close to the level of effort to fix it. The existence of an easily implemented workaround can also lead to this priority level instead of a higher priority.
