Description Harshal Patil 2021-04-06 10:07:17 UTC
Description of problem:

The current implementation of the auto node sizing is not overriding user specified values for system reserved. 

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


How reproducible:


Steps to Reproduce:
1. 
apiVersion: machineconfiguration.openshift.io/v1
kind: KubeletConfig
metadata:
  name: single-node-reserve-sys-mem
spec:
  machineConfigPoolSelector:
    matchLabels:
      pools.operator.machineconfiguration.openshift.io/master: ""
  kubeletConfig: 
    systemReserved:
      memory: 3Gi



Actual results:
When the MCO has done rolling out that kubeletconfig, the nodes won't come up with 3Gi systemd reserved. 

Expected results:
Nodes should have come up with user specified system reserved.
