Known issues​

1. Cluster upgrade stuck after the first node is upgraded​

tip

To prevent this issue from occurring, label the local-kubeconfig secret before starting the upgrade process. kubectl label secret local-kubeconfig -n fleet-local cluster.x-k8s.io/cluster-name=local

When upgrading a Harvester cluster from v1.2.2 or v1.3.0 to v1.3.1, the upgrade process becomes stuck after the first node is upgraded.

Example:

To resolve this issue, perform the following steps:

  1. Identify the cluster status:

    kubectl get clusters.provisioning.cattle.io local -n fleet-local -o yaml

    Example output:

    ...
      - lastUpdateTime: "2024-06-18T23:37:39Z"
        message: 'configuring bootstrap node(s) custom-9cb22ccf7984: waiting for kubelet
          to update'
        reason: Waiting
        status: Unknown
        type: Updated
      - lastUpdateTime: "2024-06-18T23:37:39Z"
        message: 'configuring bootstrap node(s) custom-9cb22ccf7984: waiting for kubelet
          to update'
        reason: Waiting
        status: Unknown
        type: Provisioned

    If the output includes the message waiting for kubelet, continue to the next step.

  2. Check the capi-controller-manager pod's logs:

    kubectl logs -n cattle-provisioning-capi-system deployment/capi-controller-manager

    If the output is similar to the following example, the issue likely exists in the cluster.

  3. Apply the following workaround to resume the upgrade:

    Kill and restart the capi-controller-manager pod.

    Example:

    kubectl rollout restart deployment/capi-controller-manager -n cattle-provisioning-capi-system

2. Automatic image cleanup is not functioning​

Because the published Harvester ISO contains an incomplete image list, automatic image cleanup cannot be performed during an upgrade from v1.2.2 to v1.3.1. This issue does not block the upgrade, and you can use this script to manually clean up container images after the upgrade is completed. For more information, see issue #6620.
