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.

   .. note::

      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.)

Procedure
---------

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

   .. note::

      For versions earlier than MRS 1.7.2, see :ref:`Synchronizing Cluster Configurations <mrs_01_0259>`.

#. 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.
