Doc Text:
.Pool size can now be customized when deploying clusters with `ceph-ansible` Previously, the `ceph-ansible` utility set the pool size to 3 by default and did not allow the user to change it. However, in Red Hat OpenStack deployments, setting the size of each pool is sometimes required. With this update, the pool size can be customized. To do so, change the `size` setting in the `all.yml` file. Each time, the value of `size` is changed, a new size is applied.

Description Yogev Rabl 2018-06-28 16:23:31 UTC 
Description of problem:
In earlier versions of Openstack TripleO the puppet Ceph module allowed the operator to set the size of each pool. 
Ceph ansible sets the pool size to 3 by default and doesn't allow to customize it.

Bara, lgtm, thanks.
Comment 14 Sébastien Han 2018-11-20 17:56:20 UTC 
Maybe you can also add that each time the "size" value is changed, a new size will be applied. Thanks

I don't see an "External Tracker" that points at a GitHub pull request that landed between v3.2.0rc3 and v3.2.0rc4. Would you please tell me which GitHub pull request fixes this BZ in v3.2.0rc4?
