You can find guidelines in the Install Guide [1] for OpenStack in common and in the DevStack manual [2] for DevStack multi node environment.

[cid:image001.png@01D064D6.7A9C7FC0] My question is: • what are the services needed to start when openstack block storage as a saperate node apart from controller and compute node. • Could anyone help me how to setup manually and how to set up via devstack (configurations in local.conf file for cinder-volume only) Thanks and Regards, Raghavendrachari kamsali | Software Engineer II | Embedded Computing Artesyn Embedded Technologies | 5th Floor, Capella Block, The V, Madhapur| Hyderabad, AP 500081 India T +91-40-66747059<tel:%2B91-40-66747059> | M +919705762153<tel:%2B919705762153> _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org<mailto:openstack@lists.openstack.org> Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
