Blueprint changed by James Page: Whiteboard changed: UDS Discussion: Glance has supported ceph as a a backend storage for the past couple of releases of openstack. We should make it as easy as possible for users to use ceph with glance. This could be an alternative for users who do not want to setup for a full swift setup. As discussed, the lack of Ceph intrgration with Keystone does not make the swift replacement story compelling anywhere else than as, eventually, a backend for glance. Ceph has also worked on integrating RBD with nova-volume (now cinder) which makes it a nice candidate to provide a scalable backend for it. Conclusion: - we should make sure Ceph is well integrated on Ubuntu - we should concentrate on the Ceph RBD integration with OpenStack Cinder TODO Upstream CEPH changed significantly just now. keystone+ceph RADOS: no good story here right now Arch issues are bugs. User Stories: - Tony decides that he would like to use an alternative to Swift to support object storage in OpenStack. Ubuntu provides Ceph as a supported technology so he is able to integrate this into his customized OpenStack deployment. + Tony decides that he would like to use an alternative to Swift to support object storage in OpenStack.

He selects Ceph on Ubuntu as a Canonical supported offering to meet this requirement. June wants to get started quickly with Ceph; using the latest charm from the Juju charm store she is quickly and easily able to get a running Ceph cluster on bare metal using MAAS. Nijaba (!) wants to have a scalable and open source back-end for Cinder (ex nova-volume) which Ceph RBD could provide nicely. Phil would like to use Ceph RADOS as a backend for Glance. - Assumptions: - Ceph will not replace swift as the default supported image store during 12.10 - All testing will be functional and not performance/benchmark driven. - Ceph will remain the Ubuntu main Test Plans: - Test Ceph using XFS based storage. - Test Ceph using BTRFS based storage. - Test Charm Release Note: Ubuntu 12.10 provides Ceph 0.4x, a distributed object storage technology. Ceph has been tested with XFS and BTRFS during this development cycle.
