I think you should try Pacemaker A/P configuration with same hostname in cinder.conf. That's the only safe option here. I don't quite understand John's idea of how virtual IP can help with c-vol, as this service only listens on AMQP queue. I think VIP is useful only for running c-api service. __________________________________________________________________________ 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
