I’m not sure how well that works if the cluster is only designed to be temporary, since removing a productive node from a cluster is a bit risky

Good callout. Just did some reading on the concept of maintaining a quorum, which I didn’t know about. Definitely need to be careful if I go with that approach, but it does sound interesting! I’m not entirely opposed to leaving the old laptop as a node and then using it for experimental stuff or maybe running just one specific standalone service on it after moving the critical stuff to the new server.
