Diagnostic Steps

• Check for openshift-debug-node namespaces:

  $ oc get ns | grep "openshift-debug-node"
  openshift-debug-node-7k4p88q4kk                    Active        78d
  openshift-debug-node-7shqwcjgwf                    Active        57d
  openshift-debug-node-c5zp2njj2c                    Active        48d
  openshift-debug-node-fr768h6jw2                    Active        48d
  openshift-debug-node-gxtb2                         Active        21d
  openshift-debug-node-hz2z7r9vrs                    Active        26h
  openshift-debug-node-pdlxr86vtp                    Active        57d
  openshift-debug-node-t4vp6cgxzl                    Active        62d
  openshift-debug-node-z2n2s6gmvq                    Active        86d
  openshift-debug-node-zjlvczvwfd                    Active        48d
  

• Check for pods running on the openshift-debug-node namespaces:

  $ oc get pods -A | grep "openshift-debug-node"
  [empty output]
