Ceph Storage Backend for Cinder
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.
juju deploy cinder juju deploy -n 3 ceph juju deploy cinder-ceph juju add-relation cinder-ceph cinder juju add-relation cinder-ceph ceph
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.
