I would like very much to specify pg_num and pgp_num for the default pools, but they are defaulting to 64 (no OSDs are defined in the config file). I have tried using the options indicated by Artem, but they didn't seem to have any effect on the data and rbd pools which are created by default. Is there something I am missing?
