I created a node to join the existing cluster with some wrong parameters (I set the same host name in the two servers), so I want to remove this node permanently. I executed the command below after I terminated the service,
cockroach node decommission 5 --wait=live --certs-dir=certs --host=60.x.x.x
and then I can see the node 5 was moved into the Decommissioned nodes list in admin UI. Could someone please tell me how to completely remove node 5, so that it shall be disappeared in the decommissioned nodes list of admin UI ?
