http://www.sebastien-han.fr/blog/2013/06/03/ceph-integration-in-openstack-grizzly-update-and-roadmap-for-havana/
suggests it is possible to run openstack instances (not only images) off
of RBDs in grizzly and havana (which I'm running), and to use RBDs in
lieu of a shared file system.
I've followed
http://ceph.com/docs/next/rbd/libvirt/
but I can only get boot-from-volume to work. Instances still are being
housed in /var/lib/nova/instances, making live-migration a non-starter.
Is there a better guide for running openstack instances out of RBDs, or
is it just not ready yet?
Thanks,
-Gaylord
