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.
