Hi All, We're running Firefly on the ceph side and Icehouse on the OpenStack side & I've pulled the recommended nova branch from https://github.com/angdraug/nova/tree/rbd-ephemeral-clone-stable-icehouse according to http://ceph.com/docs/master/rbd/rbd-openstack/#booting-from-a-block-device: "When Glance and Cinder are both using Ceph block devices, the image is a copy-on-write clone, so it can create a new volume quickly" I'm not seeing this, even though I have glance setup in such away that nova does create copy on write clones when booting ephemeral instances of the same image. Cinder downloads the glance RBD than pushes it back up as full copy. Since Glance -> Nova is working (has the show_image_direct_url=True etc...) I suspect a problem with my Cinder config, this is what I added for rbd support: [rbd] volume_driver=cinder.volume.drivers.rbd.RBDDriver rbd_pool=volumes rbd_ceph_conf=/etc/ceph/ceph.conf rbd_flatten_volume_from_snapshot=false rbd_max_clone_depth=5 glance_api_version=2 rbd_user=<USER> rbd_secret_uuid=<UUID> volume_backend_name=rbd Note it does *work* just not doing CoW. Am I missing something here? Thanks, -Jon _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
