Rancher is stuck in "Reconciling" with the message of "Draining node".
This came about when a cluster was updated from v1.30 to v1.31 RKE2 with the drain nodes option on and probably because the control planes have an overarching IP governed by keepalived, so if one goes down, the other takes over (yes, not the best way. Compromises-R-Uz) but that's not related to whether a service is running.
It got as far as the first control plane, did some draining, lost contact with the service and that was about it (I surmise).
Since then, nothing has moved the "Draining node" onwards. There was a manual draining done, which was successful, RKE2-server stopped and started, server rebooted, attempt at restoring a snapshot, rancher cluster upgrade cancel...
Does anyone know how to stop the update and/or get the "Draining node" out of the way so the node reconciles? I'm a little stuck with how to get this cluster properly functioning again.
