Section Number and Name: 
2.3

Describe the issue: 
According the documentation, only doing these steps the new node should be included in the OSE cluster.

Suggestions for improvement:
Update the documentation or update the OSE to work according the documentation. 

Additional information: 
In my case, to work was necessary:

- change the file /root/.config/openshift/installer.cfg.yml
- execute again the installer oo-install-ose

Ps.: My doubt is if the script will not change any previews configuration, btw works fine and now with a new member node.
