    Description

      It would be nice if "lfs setstripe" and "lfs migrate" could pick x out of y given OSTs (y>x). AKA you tell it to stripe across 8 OSTs, give a list of 25 and "lfs migrate" pick the 8 OSTs with most space available. Currently it breaks with x != y.

      For files with overstriping, "lfs setstripe -o x,y,z -C N" should repeat the x,y,z pattern until all N OSTs are selected.
