[Bug 1098314] [NEW] pg_num inappropriately low on new pools

[Paul Collins]

Public bug reported:

Version: 0.48.2-0ubuntu2~cloud0

On a Ceph cluster with 18 OSDs, new object pools are being created with
a pg_num of 8.  Upstream recommends that there be more like 100 or so
PGs per OSD: http://article.gmane.org/gmane.comp.file-
systems.ceph.devel/10242

I've worked around this by removing and recreating the pools with a
higher pg_num before we started using the cluster, but since we aim for
fully automated deployment (using Juju and MaaS) this is suboptimal.
