Data Placement
==============
-When you create pools and set the number of placement groups for the pool, Ceph
-uses default values when you don't specifically override the defaults. **We
-recommend** overridding some of the defaults. Specifically, we recommend setting
-a pools 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.

-
-:Description: The minimum number of replicas for a ruleset.
-:Type: 32-bit Integer

-
-
-``osd pool default size``

-
-``osd pool default min size``
-
-:Descrption: Sets the minimum number of written replicas for objects in the
- pool in order to acknowledge a write operation to the client.
- If minimum is not met, Ceph will not acknowledge the write to the
- client. This setting ensures a minimum number of replicas when
- operating in ``degraded`` mode.
-
-:Type: 32-bit Integer
-:Default: ``0``, which means no particular minimum. If ``0``,
- minimum is ``size - (size / 2)``.
