It uses very aggressive caching to get decent speed. Take a decent
database box with 32GB RAM, assume MySQL is underworked at the moment
and using 11GB then your power quits on ya.... chances are you just
lost 21GB of your "most used" data which would probably be most of
/var/lib/mysql ;)
Under no circumstances is XFS safe without a UPS. It has not improved
in this regard and probably never will. Anyone advising you to deploy
XFS in a production environment without UPS on 'critical' data is a
fool.
Just my two cents, of course, and lets get back on topic? :)
