   9 Ceph uses default values to determine how many placement groups (PGs) will be
  10 assigned to each pool. We recommend overriding some of the defaults.
  11 Specifically, we recommend setting a pool's replica size and overriding the
  12 default number of placement groups. You can set these values when running
  13 `pool`_ commands. You can also override the defaults by adding new ones in the
  14 ``[global]`` section of your Ceph configuration file.
