How to restart kubernetes nodes?

Question

The status of nodes is reported as unknown

\"conditions\": [
          {
            \"type\": \"Ready\",
            \"status\": \"Unknown\",
          


        

Answer 1

I had an onpremises HA installation, a master and a worker stopped working returning a NOTReady status. Checking the kubelet logs on the nodes I found out this problem:

failed to run Kubelet: Running with swap on is not supported, please disable swap! or set --fail-swap-on flag to false

Disabling swap on nodes with

swapoff -a

and restarting the kubelet

systemctl restart kubelet

did the work.
