I just got this info at XEN:
> LVM does not honor write-barriers.

Then I searched and found a thread were Eric also talked:

If I understand correctly, turning off disk cache write cache should be 
enough to be save, even when using LVM. Is it really XEN that messed the 
disk, or something else? Could the Areca controller driver do something 
wrong? I'd really love to get a stable and data-secure system, as you 
might understand.
