      Description of problem:

      In OpenShift 4.14 and 4.15 when running `oc logs <pod>` when the log file is rotated, it's stopped of getting more logs on the screen

A good reference for this is the pull request https://github.com/kubernetes/kubernetes/pull/115702 where it should be present in OpenShift 4.16, but not backported.

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

      4.14.z
4.15.z

      How reproducible:

      Always

      Steps to Reproduce:

          1. Generate logs in a pod
    2. Run `oc logs -f <pod>` and when the log file is rotated, not more logs are visible not following the rotated file.
    3.

      Actual results:

      `oc logs -f <pod>` is not able to follow the logs from the pod when they are rotated

      Expected results:

      `oc logs -f <pod>` is able to follow the logs from the pod when they are rotated
