cluster-node-tuning-operator in CrashLoopBackOff on CU cluster

    XMLWordPrintable

Details

    Description

      Description of problem:

      CU cluster of the Mavenir deployment has cluster-node-tuning-operator in a CrashLoopBackOff state and does not apply performance profile

      Version-Release number of selected component (if applicable):

      4.14rc0 and 4.14rc1

      How reproducible:

      100%

      Steps to Reproduce:

      1. Deploy CU cluster with ZTP gitops method
      2. Wait for Policies to be complient
      3. Check worker nodes and cluster-node-tuning-operator status 

      Actual results:

      Nodes do not have performance profile applied
      cluster-node-tuning-operator is crashing with following in logs:

      Expected results:

      cluster-node-tuning-operator is functional, performance profiles applied to worker nodes

      Additional info:

      There is no issue on a DU node of the same deployment coming from same repository, DU node is configured as requested and cluster-node-tuning-operator is functioning correctly.
