Synchronizing Cluster Configuration

Updated at: Aug 17, 2021 GMT+08:00

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.

Procedure

  1. On the cluster details page, choose Configuration > Synchronize Configuration in the upper right corner.

    Figure 1 Synchronizing configurations (using MRS 1.9.2 as an example)

  2. In the displayed dialog box, select Restart services and instances whose configuration have expired, and click OK to restart the service whose configuration has expired.

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