Synchronizing Cluster Configuration

Scenario

If Configuration Status of all services or some services is Configuration expired or Configuration failed, synchronize configuration for the cluster or service to restore its configuration status.

• If all services in the cluster are in the Configuration failed status, synchronize the cluster configuration with the background configuration.
• If all services in the cluster are in the Configuration failed status, synchronize the service configuration with the background configuration.
  

  In MRS 3.x, you cannot perform operations in this section on the management console.

Impact on the System

After synchronizing cluster configurations, you need to restart the services whose configurations have expired. These services are unavailable during restart.

Prerequisites

You have synchronized IAM users. (On the Dashboard page, click Synchronize on the right side of IAM User Sync to synchronize IAM users.)

   When Operation successful is displayed, click Finish. The cluster is started successfully.
