Billy Olsen 2e5c583a93 Add ceph-pool-weight option for calculating pgs 
Provide the weight option to the Ceph broker request API for requesting
the creation of a new Ceph storage pool. The weight is used to indicate
the percentage of the data that the pool is expected to consume. Each
environment may have slightly different needs based on the type of
workload so a config option labelled ceph-pool-weight is provided to
allow the operator to tune this value.

Closes-Bug: #1492742

Ceph Storage Backend for Cinder

Overview

This charm provides a Ceph storage backend for use with the Cinder charm; this allows multiple Ceph storage clusters to be associated with a single Cinder deployment, potentially alongside other storage backends from other vendors.

To use:

juju deploy cinder
juju deploy -n 3 ceph
juju deploy cinder-ceph
juju add-relation cinder-ceph cinder
juju add-relation cinder-ceph ceph

Configuration

The cinder-ceph charm allows the replica count for the Ceph storage pool to be configured. This must be done in advance of relating to the ceph charm:

juju set cinder-ceph ceph-osd-replication-count=3
juju add-relation cinder-ceph ceph

By default, the replica count is set to 2 replicas. Increasing this value increases data resilience at the cost of consuming most real storage in the Ceph cluster.
