Starting and Stopping an MRS Cluster

You can stop an MRS cluster using the MRS console or Manager when it is no longer needed or has been fixed due to a fault. Once stopped, the cluster's components will no longer serve external systems.

You can also restart a stopped cluster.

Prerequisites

  • The IAM users have been synchronized in advance. You can do this by clicking Synchronize next to IAM User Sync on the Dashboard page of the cluster details.
  • You have logged in to MRS Manager. For how to log in, see Accessing MRS Manager.

Starting and Stopping a Cluster on the Console

  2. On the Active Clusters page, select a running cluster and click its name to switch to the cluster details page.
  3. On the cluster details page, choose Management Operations > Start All Components or Stop All Components in the upper right corner to perform the required operation.

Starting and Stopping a Cluster Using Manager

  • MRS 3.x and later versions:
    1. Log in to Manager.
    1. Click next to the target cluster and select Stop. Enter the password of the cluster administrator. In the Stop Cluster dialog box that is displayed, click OK. Wait until the cluster is stopped.
