By accident I ran rancher-system-agent-uninstall.sh on one of my control plane nodes of a managed cluster. The cluster is brand-new, i.e. the nightly backup failed, too. I do have backups of etcd, and there are 2 more control plane nodes. The containers are still running. Is there some way to recover this host, esp the lost /var/lib/rancher/agent/rancher2_connection_info.json ?
