Troubleshooting uninstall issues

Use the following workarounds to address any problems you have with uninstalling Astra Control Center.

Uninstall of Astra Control Center fails to clean up the monitoring-operator pod on the managed cluster

If you did not unmanage your clusters before you uninstalled Astra Control Center, you can manually delete the pods in the netapp-monitoring namespace and the namespace with the following commands:

Steps

  1. Delete acc-monitoring agent:

    kubectl delete agents acc-monitoring -n netapp-monitoring

    Result:

    agent.monitoring.netapp.com "acc-monitoring" deleted

  2. Delete the namespace:

    kubectl delete ns netapp-monitoring

    Result:

    namespace "netapp-monitoring" deleted

  3. Confirm resources removed:

    kubectl get pods -n netapp-monitoring

    Result:

    No resources found in netapp-monitoring namespace.

  4. Confirm monitoring agent removed:

    kubectl get crd|grep agent

    Sample result:

    agents.monitoring.netapp.com                     2021-07-21T06:08:13Z

  5. Delete custom resource definition (CRD) information:

    kubectl delete crds agents.monitoring.netapp.com

    Result:

    customresourcedefinition.apiextensions.k8s.io "agents.monitoring.netapp.com" deleted

You can manually delete the Traefik CRDs. CRDs are global resources, and deleting them might impact other applications on the cluster.

Steps

    kubectl get crds |grep -E 'traefik'
