In the section "Configure a Block Storage service node" of the installation guide we talk about a host named "block1". This host "block1" is not mentioned in the example architecture. There are only the hosts "controller", "network" and "compute1". http://docs.openstack.org/trunk/install-guide/install/zypper/content/cinder-install-storage-node.html Also the Cinder services on the storage nodes are not mentioned in the figure "Figure 1.2. Three-node architecture with OpenStack Networking (neutron)" in "Chapter 1. Architecture". http://docs.openstack.org/trunk/install-guide/install/zypper/content/ch_overview.html Christian. -- Christian Berendt Cloud Solution Architect Mail: berendt at b1-systems.de B1 Systems GmbH Osterfeldstraße 7 / 85088 Vohburg / http://www.b1-systems.de GF: Ralph Dehner / Unternehmenssitz: Vohburg / AG: Ingolstadt,HRB 3537
