A node has /var/lib/kubelet on a separate mounted filesystem, and kubeadm reset is run. What must be done afterwards?

  1. Recreate the directory with the original ownership
  2. Restore the directory from backup
  3. Re-mount the filesystem, which reset unmounted
  4. Reformat the filesystem before rejoining
Show the answer

Answer: C. Re-mount the filesystem, which reset unmounted

kubeadm reset unmounts /var/lib/kubelet when it is a mount point, so the filesystem has to be re-mounted before the node is used again.
