Given that this will move data around (I think), should we increase the pg_num and pgp_num first and then see how it looks?
I guess adding pgs and pgps will move stuff around too, but if the PGCALC formula says you should have more then that would still be a good
start. Still, a few manual reweights first to take the 85-90% ones down might be good, some move operations are going to refuse adding things
to too-full OSDs, so you would not want to get accidentally bumped above such a limit due to some temp-data being created during moves.
that the creation (and evening out of data to the new empty PGs) doesn't kill normal client I/O perf in the meantime.
