All OpenStack Charms now contain identical tox.ini files, not to be modified or made unique within each charm repo. This is to ensure consistency across charm repos in tox target naming, approach and purpose, also giving the charm dev and test experience additional consistency. Also create empty dirs with .keep files where necessary. Some classic charms have actions and/or lib dirs, and some do not. In all classic charms, flake will now check those dirs to ensure lint coverage of existing or future content. Change-Id: I671077fbafb38bd4d2005fb2236bec416f79593f
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.
