I just got this info at XEN:
> LVM does not honor write-barriers.
Then I searched and found a thread were Eric also talked:
http://lkml.org/lkml/2008/5/16/390
http://hightechsorcery.com/2008/06/linux-write-barriers-write-caching-
lvm-and-filesystems
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.
