Re: RAID needs more to survive a power hit, different /boot layout for example (was Re: draft howto on making raids for surviving a disk crash)

Eric,

Thanks very much for your note. I'm becoming very leery of resiserfs at 
the moment... I'm about to run another series of crash tests.

Why avoid XFS entirely?

esandeen, any comments here?
Heh; well, it's the meme.
Well, yeah...
Note also that ext3 has the barrier option as well, but it is not
enabled by default due to performance concerns.  Barriers also affect
xfs performance, but enabling them in the non-battery-backed-write-cache
scenario is the right thing to do for filesystem integrity.
So if I understand you correctly, you're stating that current the most 
reliable fs in its default configuration, in terms of protection against 
power-loss scenarios, is XFS?
