which may backfire, if both nodes think the other one is down (split
brain again) and start the shutdown procedure. okay, this is a very rare
situation, and may happen only under strange load and scheduling
parameters, but it will happen as any other "very rare situation"
happens ;-). especially in HA environments they seem to happen much more
often then in simple single point of failure environments ;-) you won'Ät
loosew your filesystem, but the service is unavailable.
