This topic describes how to delete a zone from an OceanBase cluster. This operation deletes all the OBServers and data of the zone, and releases resources allocated to the host. Proceed with caution.
Prerequisites
The logged-on user has the permission to delete the cluster.
Your OceanBase cluster is managed in the current OceanBase Cloud Platform (OCP) cluster.
Otherwise, you need to use the current OCP cluster to take over your cluster. For more information, see Take over a cluster.
Check whether the zone to be deleted hosts the leader replica of the tenant. If yes, make sure that a full-featured replica of the tenant is available. Otherwise, deleting the zone will cause irreversible business interruptions.
Procedure

The Clusters page automatically appears.
The Cluster Overview page automatically appears.
In the Clusters list on this page, find the target cluster and click its name.
In the Zones list, find the row that contains the target zone, and click Delete in the Actions column.

In the dialog box, click Delete .
In the dialog box, you can click View Task to view the progress of the deletion task.
You can also choose System Management > Tasks to view the progress of the task.
When the task status is Completed , and the Zones list on the Overview page does not contain the zone, the zone is deleted.
