HA guide - could it continue using the same arch as an install guide?

[Anne Gentle]

Hi Anne - I have read the document on HA http://docs.openstack.org/trunk/openstack-ha/content/index.html
RG_
i have few questions and suggestions -
RG_
from my perspective (as a learner), i think the following should be there for us:
RG_
1) So far we followed the openstack doc for installing it in a multi node i.e from http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/ -
RG_
we have followed this doc and were successful in deploying a working openstack solution. The best part of the doc was the architect diagram explaining all the parameters like what network IP addresses each node will have etc etc
RG_
The HA doc lags the architectural diagram and should be in continuation to the doc we followed so far
RG_
for instance... what we have to do in order to make the current openstack deployment a HA taking into consideration that we have folowed ur installation document and the same multinode architecture
RG_
If i have to follow the HA doc after finishing with installation document then it makes me more confused as it does not specify properly the steps what needs to be performed on current controller node and how can i make the node HA by adding one more node to the current deployment? what needs to be changed on the current controller node and what additional needs to be performed on additional
RG_
HA node considering we followed your installation document? how does our surrent IP addresses associated with ethernet initerfaces will affect considering we have different public an private IP ranges?

Is this feedback being taken into account in the ha guide rewrite?

I believe that HA guide is completely another level of abstraction than host OS install guide. The former is rather about a world of distributed systems reflected as best practices for a Linux world, than plain how-to guide, although it may contain some useful details, even distro specific.

But bearing in mind https://youtu.be/LM1ANSge01g?t=51s and https://fghaas.github.io/openstacksummit2015-tokyo-deployment/#/1
sessions from Mitaka, I'd like to see the guide to contain only generic info and not more. Please feel free to start an openstack-dev ML thread for this topic as well.
