Re: [cinder][nova] Migrating servers' root block devices from a cinder backend to another

Assuming you're using the Libvirt driver, a hackaround here is to cold migrate the instance to another host, this refreshes the connection_info from c-api and should allow the instance to boot correctly.

Indeed I hadn’t thought of this. If migrations updates the block_device_mapping from the cinder DB entry, I will not need to make any database modifications. Thank you for your help, it’s strongly appreciated. Jean-Philippe Méthot Openstack system administrator Administrateur système Openstack PlanetHoster inc.
