Going through OpenCenter install. Everything seems to function normally. I'm able to move my controller node into "Infrastructure" and OpenCenter is happy. All nodes are green. I noticed that all actions were mysteriously fast and that my controller node did not seem to have any OpenStack packages installed. On the controller node, I run "chef-client" and notice chef was installed but the node was not assigned any roles:
root@srv1:~# chef-client Starting Chef Client, version 11.2.0 resolving cookbooks for run list: [] Synchronizing Cookbooks: Compiling Cookbooks... [2013-04-01T21:23:40+00:00] WARN: Node srv1 has an empty run list. Converging 0 resources Chef Client finished, 0 resources updated
So I check chef and find that I have 2 chef nodes created for each OpenCenter agent node: root@chef-server:~# /opt/chef-server/bin/knife node list srv1 srv1.blacksheep.com root@chef-server:~# /opt/chef-server/bin/knife node show srv1 Node Name: srv1 Environment: _default FQDN: IP: 192.168.200.101 Run List: Roles: Recipes: Platform: ubuntu 12.04 Tags: root@chef-server:~# /opt/chef-server/bin/knife node show srv1.blacksheep.com Node Name: srv1.blacksheep.com Environment: rpcs FQDN: IP: Run List: role[ha-controller1] Roles: Recipes: Platform: Tags:
I believe this is because of my mangled /etc/hosts : root@srv1:~# cat /etc/hosts 127.0.0.1 localhost.localdomain localhost srv1.blacksheep.com srv1
If I fix my /etc/hosts then this does not happen. root@srv1:~# cat /etc/hosts 127.0.0.1 localhost.localdomain localhost 192.168.200.101 srv1.blacksheep.com srv1
(remove chef nodes > remove open center node > remove chef and associated files > remove node opencenter files > re-run agent install on node > move node to "Infrastructure")

My hostname remained the same throughout : root@srv1:~# hostname srv1.blacksheep.com root@srv1:~# cat /etc/hostname srv1.blacksheep.com root@srv1:~# hostname -s srv1
The only change was to /etc/hosts
