#kubectl get nodes

To prevent a node from scheduling new pods use:
kubectl cordon <node-name>
Which will cause the node to be in the status: Ready,SchedulingDisabled.
To tell is to resume scheduling use:
kubectl uncordon <node-name>
More information about draining a node can be found here. And manual node administration here
I fixed it using:
kubectl uncordon <node-name>
