Yes, well... You're not supposed to ever use Reiser over a virtual
block device like LVM or software MD due to block device buffering
issues - Reiser, being a journaling filesystem, does not mix with disk
write buffering.
Because of this, I run reiser against two raw 30GB disks here, rather
than over an LVM or software MD append/raid. AFAIK, Hardware RAID is
fine for this application.
