=== Key New Features === * A generic image caching solution, so popular VM images can be cached and copied-on-write to a new volume. [http://docs.openstack.org/admin-guide-cloud/blockstorage_image_volume_cache.html Read docs for more info] * Non-disruptive backups [http://docs.openstack.org/admin-guide-cloud/blockstorage_volume_backups.html Read docs for more info]. * Ability to clone consistency groups of volumes [http://docs.openstack.org/admin-guide-cloud/blockstorage-consistency-groups.html Read docs for more info]. * List capabilities of a volume backend (fetch extra-specs). * Nested quotas. * Default LVM backends to be thin provisioned if available. * Corrected cinder service-list to show as Down when a driver fails to initialize. * Improved volume migration management: ** Able to see if previous migration attempt was successful ** Admins able to monitor migrations via cinder list ** New volume status of 'maintenance' to prevent operations being attempted while migration is occurring ** Improve backend volume name/id consistency after migration completes
