I know there are 2 allocation policies, contiguous and next free. Is
there any information that describes in detail how LVM determines the
extents to assign to a logical volume with it is created or extended?
For example, if the policy is "contiguous", must the LV contain all
contiguous extents or does it use a "best-case" scenario, and how would
that work? Likewise, in the "next free" scenario, is there any weight
given to contiguous space, does it automatically allocate across PVs,
