Personally I wouldn't, but it's your choice. In my opinion LVM adds another complexity layer, more stuff to manage, and you will need to keep the sizes of the various logical volumes in sync (whether you are distributed or replicated), and grow your XFS filesystems whenever you grow the logical volumes. But if you need that level of control, it's fine.
