Those 3 lines tell you pretty much all there is wrong.
You did (correctly) set the defaul pg and pgp nums to something sensible
(512) in your ceph.conf.
Unfortunately when creating the initial pool (rbd) it still ignores those
settings.
You could try to increase those for your pool, which may or may not work.
The easier and faster way is to remove the rbd pool and create it again.
This should pick up your default settings.
