Node Skipping Check

Check Items

After a cluster is upgraded, check whether there are any nodes that skip the upgrade in the cluster. These nodes may affect the proper running of the cluster.

Procedure

CCE automatically checks whether there are nodes that skip the upgrade in the cluster. Go to the node list page and confirm the nodes based on the diagnosis result. The skipped nodes are labeled with upgrade.cce.io/skipped=true.

Solution

The skipped nodes are displayed on the upgrade details page. Reset the skipped nodes after the upgrade is complete. For details about how to reset a node, see Resetting a Node.

Resetting a node will reset all node labels, which may affect workload scheduling. Before resetting a node, check and retain the labels that you have manually added to the node.
