PG Balancer Upmap mode not working

["Philippe D'Anjou" <danjou.philippe@xxxxxxxx>]

@Wido Den Hollander 

First of all the docs say: " In most cases, this distribution is “perfect,” which an equal number of PGs on each OSD (+/-1 PG, since they might not divide evenly)."

Either this is just false information or very badly stated.

I increased PGs and see no difference.

I pointed out MULTIPLE times that Nautilus has major flaws in the data distribution but nobody seems to listen to me. Not sure how much more evidence I have to show.

The % fillrate is no different than before, fluctuates hard.
