Replace a failed manager node

This section describes how to replace a failed manager node in your MOSK deployment. The procedure applies to the manager nodes that are, for example, permanently failed due to a hardware failure and remain in the NotReady state.

Note

If your cluster is deployed with a compact control plane, follow the Replace a failed controller node procedure.

To replace a failed manager node:

1. Verify that the affected manager node is in the NotReady state:

   kubectl get nodes <CONTAINER-CLOUD-NODE-NAME>
   

   Example of system response:

   NAME                          STATUS     ROLES    AGE   VERSION
   <CONTAINER-CLOUD-NODE-NAME>   NotReady   <none>   10d   v1.18.8-mirantis-1
   

2. Delete the affected manager node as described in Delete a cluster machine.

3. Add a manager node as described in Add a machine.
