Scenario: The node pool OS is not supported.
The runtime and OS vary depending on the cluster version. This issue typically occurs when a cluster of an earlier version is upgraded to v1.27 or later. For details about the mapping between CCE cluster versions and OSs, see Node OSs.

Log in to the CCE console and click the cluster name to access the cluster console. Choose Nodes in the navigation pane, view the status of the affected node pool on the Node Pools tab, and click Upgrade. Change the supported OSs based on the pre-upgrade check result, and click OK.

If there are nodes in the affected node pool, choose More > Synchronize in the operation column to synchronize the OS of the existing nodes. For details, see Synchronizing Node Pools.
