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.
