Just remember, if something goes wrong in such a way that the domain is
active on both nodes at the same time with read/write access to the
filesystem, you *will* *destroy* the filesystem and will need to restore
from backup. No amount of fscking will help you.

(I speak from bitter experience :)

Full Ack (without the bitter experience yet though).

That's why you want to have a functioning STONITH Device and redundant cluster communication ways.
