It is one of the next things on our list, and depends on the fixup of
'pg splitting' (which once worked, but other features have made it
impractical without rework). Until then we have tracker issues about

http://tracker.newdream.net/issues/1515
osd: pg split
http://tracker.newdream.net/issues/84
mon: auto adjust pg_num as pool grows
http://tracker.newdream.net/issues/85
osd: pg_num shrink
