Could you elaborate more on this? During a volume migration operation we give the driver an opportunity to more-intelligently relocate the volume's data. This is done through the migrate_volume() method defined in the driver itself. If this method exists, it will be called before falling back to a byte-for-byte copy approach - and if it succeeds the volume is considered migrated and the operation returns. Is this what you were looking for, or did you have something different in mind? -- Jon __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
