Hi Denis, I would take a look into GlusterFS with a distributed, replicated volume. We have been using it for several months now, and it has been stable. Nova will need to have the volume mounted to its instances directory (default /var/lib/nova/instances), and Cinder has direct support for Gluster as of Grizzly I believe.
