.. index:: pools; configuration

|
|
|
Ceph uses default values to determine how many placement groups (PGs) will be
|
|
assigned to each pool. 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 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.
