Terminate or delete a cluster

End a TIR Slurm Cluster when you are done with it. Terminate Cluster stops compute billing and keeps the record, and Delete Cluster removes the record. The usual order is to terminate first, keep the record in case you want to clone it, and delete it later.

Before you begin

• Update permission on Training Clusters to terminate, and the Delete permission to delete.
• Your results on a PFS or SFS mount. Running jobs end, and anything outside a mounted volume goes with the nodes.
• Every VPC IP on the cluster’s Network & Security tab finished attaching. TIR refuses both terminate and delete while an attach is in progress.

Choose between terminate and delete

Question	Terminate	Delete
Final status	Terminated	Deleted
Still in the list	Yes	No
Can still be cloned	Yes	No
Needs an acknowledgement	No	Yes
Stops compute billing	Yes	Yes

Terminate first if you might want the same setup again, because a terminated cluster can still be cloned, while a deleted one is gone for good. See Clone a cluster.

Terminate the cluster

Terminating is permanent, and a single confirmation ends the cluster. Terminate Cluster is below a divider on the Actions menu and is offered in every status.

1. Select Actions, then Terminate Cluster.
2. Confirm the dialog and select Terminate.

The status changes to Terminating, then Terminated. Terminating:

• Releases the nodes and stops compute billing for them.
• Unmounts your storage volumes and keeps them. They keep billing until you delete them yourself under Storage in the TIR sidebar.
• Detaches reserved and VPC IPs.
• Turns Login User Management off and keeps members’ home directories.
• Keeps the record in the list at Terminated, so you can still clone or delete it.

On a committed cluster, the price paid at the start covers the whole term, so nothing is refunded for the days left. See Billing and plans.

Delete the cluster

Deleting is permanent. After deletion the cluster leaves the list, and its record is gone. Delete Cluster is labelled Delete Training Cluster on the list page and is offered in every status.

1. Select Actions, then Delete Cluster (or Delete Training Cluster in the list).
2. Tick the acknowledgement for the cluster’s name.
3. Select Delete.

On an already-terminated cluster, delete is immediate, because the teardown is done, and your billing stays the same. On any other cluster, deleting runs the termination first. Either way, storage volumes are unmounted and kept, and members’ home directories stay on their volume. Compute on a Failed cluster is free, so you can delete its record whenever you like, after cloning it if you want to replace it.

Delete the storage you no longer need

Terminating and deleting keep your data. Open Storage in the TIR sidebar, review the volumes the cluster used, and delete the ones you are done with, because storage bills until you delete it. Reserved IPs are billed separately from the cluster too; see Delete a reserved IP.

Once you have deleted the volumes and reserved IPs you are done with, billing for this cluster stops, apart from anything you chose to keep. If terminate or delete is refused, see Troubleshooting TIR Slurm Cluster.
