Deleting an HPC Cluster

Scenarios

• If a cluster is no longer needed, you can delete it. If you do not select Delete cloud server when you delete the cluster, these servers will be retained and continue to be billed after the cluster is deleted. To stop billing for these cloud servers, manually delete pay-per-use servers and unsubscribe from yearly/monthly servers.
• If a cluster fails to be created, you can delete the cluster and do not select Delete cloud server. Then, use these servers to deploy a cluster again.
• If an exception occurs in a cluster and the cluster cannot be manually restored, you can delete the cluster and do not select Delete cloud server. Then, use these servers to deploy a cluster again.

Precautions

• The EIP bound to the cluster will continue to be billed after the cluster is deleted. You need to manually delete the EIP to stop billing.
• Data disks attached to nodes in the cluster will continue to be billed after the cluster is deleted, even if you select Delete cloud server when deleting the cluster. You need to manually delete the data disks to stop billing.
