10/29/2025, 6:27 AMHello. I have a 3-node Harvester cluster, where all 3 are control planes. Is it safe for me to restart rke2-server on one of the nodes, without risking stopping pods or VMs running on that host?

10/29/2025, 11:49 AMno it is not safe. restarting rke2-server will restart k8s on the node, Ideally you will want to treat the node like an appliance where you should reboot. this is due to how harvester boots and configures itself.

10/29/2025, 11:51 AMAlright. I'm asking because I needed to add a TLS SAN and I know for k3s (and rke2 i think) you can restart the service without causing pods to get restarted
