Issue/Introduction

In a Aria Orchestrator cluster environment, the System Dashboard within the Orchestrator UI incorrectly displays only two nodes, even though the cluster is intended to have three nodes. 

Environment

Aria Automation Orchestrator 8.18.1

Resolution

To resolve this issue, reinitialize the Orchestrator (vco-app) pods to refresh the cluster state and dashboard data.

 

1. Method A: Delete Pods Individually

   1. SSH into the Automation Orchestrator appliance.
   2. List the pods to get their full names:

      kubectl get pods -n prelude

   3. For each vco-app pod instance, run the delete command:

      kubectl delete pod -n prelude <vco-app-pod-name>

   4. Kubernetes will automatically recreate the pods. Monitor their status until they are running.
      
      

   Method B: Scale Deployments Down and Up

   1. SSH into the Automation Orchestrator appliance.
   2. Scale down the vco-app and UI deployments to zero replicas:

      kubectl scale deployment vco-app --replicas=0 -n prelude
      kubectl scale deployment orchestration-ui-app --replicas=0 -n prelude

   3. Wait about two minutes for the pods to terminate completely.
   4. Scale the deployments back up. Use 1 for a single-node deployment or 3 for a clustered deployment.

      kubectl scale deployment vco-app --replicas=1 -n prelude
      kubectl scale deployment orchestration-ui-app --replicas=1 -n prelude

       

2. Once the pods are healthy, log back into the System Dashboard to verify that all nodes are now correctly displayed
