.. index:: pools; configuration
When you create pools and set the number of placement groups (PGs) for each, Ceph
uses default values when you don't specifically override the defaults. **We
recommend** overriding some of the defaults. Specifically, we recommend setting
a pool's replica size and overriding the default number of placement groups. You
can specifically set these values when running `pool`_ commands. You can also
override the defaults by adding new ones in the ``[global]`` section of your
Ceph configuration file.
