Restarting a ClickHouse Cluster

If a cluster is in the unbalanced state or cannot work properly, you may need to restart it for restoration.

If your cluster is in arrears, this function may be unavailable. Please top up your account in time.

Impact on the System

  • A cluster cannot provide services during the restart. Therefore, before the restart, ensure that no task is running and all data is saved.
  • If a cluster is processing transactional data, for example, importing data, querying data, files may be damaged or the cluster may fail to be restarted once the cluster is restarted. You are advised to stop all cluster tasks before restarting a cluster.
  • If the restart fails, the cluster may be unavailable. Try again later or contact technical support.

Procedure

  1. Log in to the CloudTable console.
  2. Click in the upper left corner of the console and select a region.
  3. In the navigation tree, click Cluster Management.
  4. In the upper right corner of the cluster list, enter the name of a cluster in the search box and click .
  5. In the Operation column of the cluster, click More > Restart.
  6. In the dialog box that is displayed, select the check box and click OK to restart the cluster.
