Description Alexander Chuzhoy 2014-12-05 22:44:57 UTC 
rubygem-staypuft:  Able to start a deployment with 2 controllers. No warnings/errors given.

Environment:
openstack-foreman-installer-3.0.4-1.el7ost.noarch
openstack-puppet-modules-2014.2.6-1.el7ost.noarch
rhel-osp-installer-client-0.5.1-1.el7ost.noarch
rhel-osp-installer-0.5.1-1.el7ost.noarch
ruby193-rubygem-staypuft-0.5.2-1.el7ost.noarch
ruby193-rubygem-foreman_openstack_simplify-0.0.6-8.el7ost.noarch


Steps to reproduce:
1. Instal rhel-osp-installer.
2. Create a neutron deployment.
3. Assign only 2 controllers and start a deployment.

Result:
The deployment starts.

Expected result:
The deployment shouldn't start with 2 controllers.
Either 1 (nonHA), or at least 3.

In addition to the relase notes we should add a warning to the UI saying there should be an odd number of controller hosts added to the controller Role.

Since we moved away from ha/singe controller roles there should be an indication in the UI of what would the the end result deployment when adding a singe host and 3/5 nodes to the controller role.

Closing list of bugs for RHEL OSP Installer since its support cycle has already ended [0]. If there is some bug closed by mistake, feel free to re-open.

For new deployments, please, use RHOSP director (starting with version 7).
