vishnuvs369 opened a new issue, #12565: URL: https://github.com/apache/cloudstack/issues/12565
### problem **We attempted to scale the cluster from 8 to 9 worker nodes using the Scale Cluster option in the CloudStack UI.** The new worker VM was created successfully and is in Running state in CloudStack. However, Kubernetes does not register the new node. After the scale operation: CloudStack shows 9 worker nodes kubectl get nodes continues to show only 8 worker nodes UI status stucks on scaling. **Error observed in CloudStack Management Server logs:** ERROR ... Unexpected exception while executing ScaleKubernetesClusterCmd at KubernetesClusterResourceModifierActionWorker.removeSshFirewallRule at KubernetesClusterScaleWorker.scaleKubernetesClusterIsolatedNetworkRules ### versions Environment details: CloudStack version: 4.19.0.1 Cluster type: CloudStack Kubernetes Service (CKS) Initial cluster size: 1 Control Plane 8 Worker Nodes (working fine) Scale target: 9 Worker Nodes Global setting cloud.kubernetes.cluster.max.size was increased from 10 to 50 prior to scaling. ### The steps to reproduce the bug **Steps to Reproduce** Deploy a Kubernetes cluster using CloudStack Kubernetes Service (CKS) on CloudStack 4.19.0.1 with the following configuration: 1 Control Plane node 8 Worker nodes From the CloudStack UI, navigate to: Kubernetes → Clusters → <cluster-name> → Scale Cluster Scale the cluster by increasing the worker node count from 8 to 9 and submit the scale operation. Observe the following behavior: The new worker VM is created successfully and shows Running state in CloudStack. The scale task stucks on scaling. kubectl get nodes still showing node count as 8 ### What to do about it? is there any workaround to resolve this without restarting the cluster -- This is an automated message from the Apache Git Service.
