Drain controller seems to be ignoring any error code returned by drain.sh script. Therefor it's possible to scale down from 2 to 0 replica and delete all PersistenVolumes with messages. Even though the script is complaining about missing endpoint to resolve IP.
Expected: No persistent message is lost upon scale to 0.
