Issue

• How to increase logs verbosity for machine API.
• Debug log level for openshift-machine-api.

Resolution

1. Unmanage machine-api-operator.

$ oc patch clusterversion/version --type json -p '[{"op":"add","path":"/spec/overrides","value":[{"kind":"Deployment","group":"apps","name":"machine-api-operator","namespace":"openshift-machine-api","unmanaged":true}]}]'

2. Scale down machine-api-operator. But before scaling down the deployment/machine-api-operator replicas=0 check the replicas count. then proceed with below.

$ oc -n openshift-machine-api scale deployment/machine-api-operator --replicas=0

3. Edit machine-api-controllers deployment and replace any --v=3 (3 may be a lower number) with --v=8 (it can be seen as part of different args: arrays).

$ oc -n openshift-machine-api edit deployment/machine-api-controllers

4. Wait until the new machine-api-controllers pod starts. Then scale-up again the deployment/machine-api-operator replicas and patch the clusterversion/version again to manage.
