Bionic, being the next LTS, is important to enable for dev and test as early as possible ahead of 18.02. Zesty goes EOL in Jan 2018. The next stable charms release (18.02) will not provide Zesty series support, as it was an interim (non-LTS) release. Change-Id: I5117822323d86c92c3060755cdec0bbb5b5ddfc2 |

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.
