When your focus is availability, restarting on the node that doesn't
have the error makes sense. As does alerting the admin there's a
problem. Like e.g. drbd's
handlers {
  split-brain "/usr/lib/drbd/notify-split-brain.sh root";

The difference between "restating and failing" and "restarting and
generating alert and failing" is the alert flood.
