Hello,<br>
<br>
We want to implement a production HA OpenStack environment based on<br>
Grizzly release .<br>
We went over the "Introduction to OpenStack High Availability" guide<br>
(<a href="http://docs.openstack.org/trunk/openstack-ha/content/ch-intro.html" target="_blank">http://docs.openstack.org/trunk/openstack-ha/content/ch-intro.html</a>) and we<br>
have few questions:<br>
1. Does Pacemaker is the preferred tool to base OpenStack HA solution on ?<br></blockquote><div><br></div></div><div>It's documented but there's no preference. I want to address your assumption that the OpenStack docs site endorses particular solutions preferentially - that is not the case. We collect documents that should help others answer their questions as they approach a complex system.</div>

2. Are there any alternatives for Pacemaker ?<br></blockquote><div><br></div></div><div>Surely there are.</div><div class="im"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
3. Will Pacemaker be used as official HA solution in Havana as well ?<br></blockquote><div><br></div></div><div>As I indicated above, a document hosted on the <a href="http://docs.openstack.org" target="_blank">docs.openstack.org</a> site does not connote an "official" endorsement. Nor does it indicate a roadmap for future releases. </div>

4. Is the guide mentioned above can be used in continue to the basic<br>
Grizzly installation guide or any additional steps should be performed<br>
before ?<br></blockquote><div><br></div></div><div>We had a thread on the openstack-docs mailing list about this particular doc updates for Grizzly:</div><div><a href="http://lists.openstack.org/pipermail/openstack-docs/2013-April/001547.html" target="_blank">http://lists.openstack.org/pipermail/openstack-docs/2013-April/001547.html</a> In it you'll find that the current active / passive mode is not completely documented. The document is mean to help with considerations. As you can see from the discussion there's no "one right way." Florian Haas, the original author, addresses that in this response: <a href="http://lists.openstack.org/pipermail/openstack-docs/2013-April/001570.html" target="_blank">http://lists.openstack.org/pipermail/openstack-docs/2013-April/001570.html</a>.</div>

5. Does the guide assume 2 controller nodes, meaning Pacemaker cluster will<br>
be installed on 2 controller nodes to support HA ?<br></blockquote><div><br></div></div><div>I believe the document prepares MySQL and RabbitMQ for Pacemaker HA. That doesn't assume 2 controller nodes does it? Perhaps Florian or Emilien can comment. </div>

6. Is there a possibility to configure HA for the Network Node ? If yes ,<br>
can you point us to any relevant references.<br></blockquote><div><br></div></div><div>I don't know of any.</div><div><br></div><div>Hope this helps,</div><div>Anne</div><div class="im"><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
