Deleting a Cluster¶
Precautions¶
Deleting a cluster will delete the workloads and Services in the cluster, and the deleted data cannot be recovered. Before performing this operation, ensure that related data has been backed up or migrated.
If you choose to delete a cluster with the nodes in it, the system disks and data disks attached to the nodes will also be deleted. Back up data before the deletion.
If you delete a cluster that is not running (for example, unavailable), associated resources, such as storage and networking resources, will remain.
Deleting a Cluster¶
Important
A hibernated cluster cannot be deleted. Wake up the cluster and try again.
Log in to the CCE console. In the navigation pane, choose Clusters.
Locate the cluster to be deleted, click ... to view more operations on the cluster, and choose Delete Cluster.
In the displayed Delete Cluster dialog box, select the resources to be released.
Delete cloud storage resources associated with workloads in the cluster.
Note
When deleting underlying cloud storage resources bound to storage volumes in a cluster, pay attention to following constraints:
The underlying storage resources are deleted according to the reclamation policy you defined for the storage volumes. For example, if the reclamation policy of storage volumes is Retain, the underlying storage resources will be retained after the cluster is deleted.
If there are more than 1000 files in the OBS bucket, manually clear the files and then delete the cluster.
If the storage volume's reclamation policy is set to Retain, the following table lists the method of deleting PVs based on their type.
PV Type
Associated Underlying Storage
Whether to Delete Underlying Storage
EVS
Disks
Yes
SFS
SFS Capacity-Oriented
Yes
OBS
OBS buckets or parallel file systems
Yes
SFS Turbo
SFS Turbo file systems
Yes
Local PV
Logical volumes mounted to the node
Determined based on the policy selected when the cluster is deleted.
If you choose to retain the node, the logical volumes will not be deleted. If you choose to delete or reset the node, the logical volumes will be deleted.

Delete network resources such as load balancers in a cluster. (Only automatically created load balancers will be deleted).
Enter DELETE and click Yes to start deleting the cluster.
The delete operation takes 1 to 3 minutes to complete.
