Bobb, finally I had some time to check this BZ, sorry for the delay. There seems to be some misunderstanding of some terms (at least in the 3.2. Web Administration Roles chapter). The usage of "role/roles" seems to me to be used slightly incorrectly for both Ansible roles[1] and Ansible groups[2] there. * Groups[1] (in Ansible) are some sort of classification of hosts in the inventory file. You will group hosts with the same/similar purpose together and then for example launch some task on particular group. * Roles[2] are bunch of task combined together to perform some comprehensive functionality (this is quite simplified description, but hopefully it make sense). And for example, in some playbook, you will say something like: on hosts from group A run tasks from Roles X and Y. In tendrl-ansible, there are two roles[3]: * tendrl-ansible.tendrl-server * tendrl-ansible.tendrl-storage-node The tendrl-ansible.tendrl-server role contains tasks required for installation and configuration of RHGS Web Administration server. The tendrl-ansible.tendrl-storage-node contains tasks required for installation and configuration of RHGS Web Administration agents on Gluster Storage Nodes. Now there might be some confusion, because the example playbook site.yml.sample[4] expects, that the inventory file will contain hosts divided into two groups: tendrl-server and gluster-servers. The group tendrl-server is not the same as role tendrl-ansible.tendrl-server! Nonetheless the role tendrl-ansible.tendrl-servrer contains tasks meant for host from tendrl-server group. It is expected, that group tendrl-server will contains only one host (the RHGS Web Administration Server), while the gluster-servers group will contain all Gluster Storage servers.

Also all the comments and issues raised in this bug are involved.
