Hibernating and Waking Up a Cluster

Scenario

If you do not need to use a cluster temporarily, hibernate the cluster.

After a cluster is hibernated, resources such as workloads cannot be created or managed in the cluster.

A hibernated cluster can be quickly woken up and used properly.

Constraints

• During cluster wakeup, the master node may fail to start due to insufficient resources, which leads to a cluster wakeup failure. In this case, wait for a while and try again.
• After a cluster is woken up, it takes 3 to 5 minutes to initialize data. Deliver services after the cluster runs properly.

Hibernating a Cluster

1. Log in to the CCE console. In the navigation pane, choose Clusters.
2. Locate the cluster to be hibernated, click ... to view more operations on the cluster, and choose Hibernate.
3. In the dialog box displayed, check the precautions and click Yes. Wait until the cluster is hibernated.

Waking Up a Cluster

1. Log in to the CCE console. In the navigation pane, choose Clusters.
2. Click Wake Up in the row of the target cluster.
3. When the cluster status changes from Waking up to Running, the cluster is woken up. It takes about 3 to 5 minutes to wake up the cluster.
