Resuming a node brings it out of maintenance mode and schedulable again.

Resume a node from maintenance from either the web console or the CLI.

Resuming a node from maintenance mode in the web console

Resume a node from maintenance mode using the Options menu kebab found on each node in the ComputeNodes list, or using the Actions control of the Node Details screen.

Procedure
  1. In the container-native virtualization console, click ComputeNodes.

  2. You can resume the node from this screen, which makes it easier to perform actions on multiple nodes in the one screen, or from the Node Details screen where you can view comprehensive details of the selected node:

    • Click the Options menu kebab at the end of the node and select Stop Maintenance.

    • Click the node name to open the Node Details screen and click ActionsStop Maintenance.

  3. Click Stop Maintenance in the confirmation window.

The node becomes schedulable, but virtual machine instances that were running on the node prior to maintenance will not automatically migrate back to this node.

Resuming a node from maintenance mode in the CLI

Resume a node from maintenance mode and make it schedulable again by deleting the NodeMaintenance object for the node.

Procedure
  1. Find the NodeMaintenance object:

    $ oc get nodemaintenance
  2. Optional: Insepct the NodeMaintenance object to ensure it is associated with the correct node:

    $ oc describe nodemaintenance <node02-maintenance>
    Name:         node02-maintenance
    Namespace:
    Labels:
    Annotations:
    API Version:  kubevirt.io/v1alpha1
    Kind:         NodeMaintenance
    ...
    Spec:
      Node Name:  node02
      Reason:     Replacing node02
  3. Delete the NodeMaintenance object:

    $ oc delete nodemaintenance <node02-maintenance>
