I’ve done this many times. Here are the steps for you:
tiup cluster scale-in --node 10.0.1.5:20160

Refer to this document:

  1. If the node cannot be started, it can only be forcibly deleted (forced offline).
  • Forced offline
tiup cluster scale-in <clusterName> -N <IP:port> --force
  • Clean up region metadata
curl -X DELETE http://${HostIP}:2379/pd/api/v1/admin/cache/region/{region_id}
  1. If the node can still be started, it can be scaled down in the normal way.
