urgent need for help, production cluster down. I was trying to update rancher downsteam cluster from GUI and it was some how one of the etcd nodes stuck with draining node (after the two first nodes was upgraded whit out issues). in my attempt to get it back up I made a restore snapshot from GUI but know nothing is running 😞 and I dont know what to do

Hi @important-architect-36609, I'm certain this is not the most efficient venue for P1 production issues. That said, if you are still having trouble getting your cluster back online, you will need to provide more information in order for anyone to be able to help. One question I have is, did you take backups just prior to the upgrade; and did you take a backup just before your attempted restore?
