Description of problem: Setting maxReplicas equal to minReplicas, will result in "group size not found". Version-Release number of selected component (if applicable): $ bin/openshift-install version bin/openshift-install v0.5.0-master-2-g78e2c8b144352b1bef854501d3760a9daaaa2eb0 Terraform v0.11.8 How reproducible: Always Steps to Reproduce: 1. Create clusterautoscaler resource 2. Create machineautoscaler resource, set maxReplicas=2, minReplicas=2 3. Create pod to scale up the cluster 4. Check logs Actual results: Logs output "group size not found" $ oc get machineautoscaler autoscale-us-east-2a-85rjb -o yaml apiVersion: autoscaling.openshift.io/v1alpha1 kind: MachineAutoscaler metadata: creationTimestamp: 2018-12-04T04:50:03Z finalizers: - machinetarget.autoscaling.openshift.io generateName: autoscale-us-east-2a- generation: 1 name: autoscale-us-east-2a-85rjb namespace: openshift-cluster-api resourceVersion: "193797" selfLink: /apis/autoscaling.openshift.io/v1alpha1/namespaces/openshift-cluster-api/machineautoscalers/autoscale-us-east-2a-85rjb uid: 102eed94-f780-11e8-ba7f-0644519597a8 spec: maxReplicas: 2 minReplicas: 2 scaleTargetRef: apiVersion: cluster.k8s.io/v1alpha1 kind: MachineSet name: qe-zhsun-worker-us-east-2a status: {} $ oc logs -f cluster-autoscaler-default-77f884d74b-527bq E1204 08:26:01.996252 1 utils.go:467] Error while checking node group size qe-zhsun-worker-us-east-2a: group size not found E1204 08:26:01.996545 1 utils.go:467] Error while checking node group size qe-zhsun-worker-us-east-2b: group size not found E1204 08:26:01.996678 1 utils.go:467] Error while checking node group size qe-zhsun-worker-us-east-2c: group size not found Expected results: Cluster can scale up and allow some group has fixed node number.
