Kubernetes adopts a declarative mechanism to define the desired state of a resource and ensures that the actual state of the resource matches the desired state. When the actual state of a resource does not match the user-defined desired state, Kubernetes automatically performs necessary changes to ensure consistency between the two. This process is called reconciliation.
When you need to maintain the cluster or troubleshoot issues, you can Suspend reconciliation. Once suspended, the cluster state will not be automatically adjusted even if its actual state deviates from the expected one. Once you finish your operations, you can Resume reconciliation to restore the cluster state to the expected one.
Precautions
You cannot switch the AKE mode to high availability or upgrade the AKE version when the management cluster is in the Reconciliation suspended state.
Suspending reconciliation may cause the resource state of the cluster to be inconsistent with the desired state. Avoid keeping the cluster in a suspended reconciliation state for an extended period.
Procedure
Click Settings > Management cluster to enter the management cluster details interface.
Click ... in the upper right corner and select Suspend reconciliation or Resume reconciliation.
