There's a lot that could be going on in the background, but if it were me, I'd probably already have powered down the node, and wiped the disks/OS before doing it this way.

(assuming you're running on bare metal)

Just make sure it's not the only control plane node or something

you should be able to check with

kubectl get nodes

I was able to delete the node and then add it back with a new/diff name

Using the same node name did not work

any idea how to fix that?

Search through the support bundle to find them?

I wish there was some docs on how things are linked.
