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, etc? Thanks! Anthony
