<div dir="ltr"><div class="gmail_default" style="font-family:'courier new',monospace">Hi All,</div><div class="gmail_default" style="font-family:'courier new',monospace"><br></div><div class="gmail_default" style="font-family:'courier new',monospace">
I am trying (keyword trying) to get a highly available cluster going. Currently I have most of the services needed (mysql, rabbitmq, glance, keystone, etc.) configured as resources in pacemaker and that works quite nicely. Now I need to figure out networking.</div>
<div class="gmail_default" style="font-family:'courier new',monospace"><br></div><div class="gmail_default" style="font-family:'courier new',monospace">I have 2 servers with 2 NICs, one NIC is a public interface and the other is on an internal network. This is likely to increase to three servers in the near future to help with quorum/split brain issues. I plan on these servers being a combination control/networking hosts. On the internal network I have several compute nodes.</div>
<div class="gmail_default" style="font-family:'courier new',monospace"><br></div><div class="gmail_default" style="font-family:'courier new',monospace">What are some of my networking options? </div><div class="gmail_default" style="font-family:'courier new',monospace">
<br></div><div class="gmail_default" style="font-family:'courier new',monospace">Quantum seems out because it looks like it requires 3 NICs. I initially tried adding my public IP to external bridge interface hoping I could get away with 2 NICs but I could't get it to work. If someone could explain why quantum requires 3 interfaces that would be great.</div>
<div class="gmail_default" style="font-family:'courier new',monospace"><br></div><div class="gmail_default" style="font-family:'courier new',monospace">That leaves nova-network. Seeing my compute nodes are behind the control/networking nodes does that mean multi_host is out of the question? If so that really only leaves creating a VIP in pacemaker and moving it around with nova-network with pacemaker correct?</div>
