* votes="1"

Qdiskd does not and can not prevent CMAN from fencing the dead portion
of the cluster during startup.

Not true anymore as of 5.1, but changing the order will not prevent cman
from fencing the dead node.

<fenced clean_start="1" /> will prevent fencing dead nodes on startup,
but is dangerous to use.
