But the more direct a system, the more reliable it is. Basic scientific principle. To me, LVM just adds a function (expansion) which should be in the RAID module (and likely soon will be), yet adds a whole 'nother layer of complexity. No thanks. BTRFS addresses all these issues, but I was an early adopter and got burned by the loss of my data at a crucial point.
