Delete a faulty follower OCP cluster

This topic describes how to delete a follower OCP cluster that has a heartbeat timeout exception.

Background

Scenario:

After a failover occurs, OCP clusters in the OCPs list no longer report heartbeat information to the original leader OCP cluster. Therefore, the OCPs list of the original leader OCP cluster may contain an OCP cluster whose heartbeat detection timed out. In this case, information of other OCP clusters is still stored in the original leader OCP cluster.

You need to delete information of the OCP clusters and the OceanBase clusters managed by the original leader OCP cluster from the original leader.

Prerequisites

• You have logged in to the OceanBase Cloud Platform (OCP) console and been assigned the ADMIN role.

• You have registered OCP clusters. For more information, see Register an OCP cluster.

• The OCPs list of the current OCP cluster contains an OCP cluster that has a heartbeat timeout exception. One of the following conditions is met:

  • The current OCP cluster cannot access the MetaDB of the OCP cluster that has a heartbeat timeout exception.

  • The current OCP cluster can access the MetaDB of the OCP cluster that has a heartbeat timeout exception, but its leader is no longer the current OCP cluster.

Delete an OCP cluster

1. Log on to the OCP console.

2. In the left-side navigation pane, choose System Management > OCP Multi-cluster Mode .
