Hi Thomas, What happens if you run "ceph cephadm check-host <hostname>" for one of the hosts that is offline (and if that fails "ceph cephadm check-host <hostname> <ip-addr>")? Usually, the hosts get marked offline when some ssh connection to them fails. The check-host command will attempt a connection and maybe let us see why it's failing, or, if there is no longer an issue connecting to the host, should mark the host online again.
