.. 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.
