<p>well, I can add one more controller this is not an issue,<br>
</p>
<p>there is any technical doc? I understood the architecture but I have hard time to implement it <br>
</p>
<p>there is any reference to CentOS 7? I need it for Juno <br>
</p>
<p>currently I have issues with Galera sync, there is no technical guide about Galera and Centos 7<br>
</p>
<p><br>

<p>Thanks,<br>

<div>You can find the default RDO HA config with 3 controllers here:

<div class="">The doc is not completely up to date for MariaDB, Neutron and AMQP.</div>

I think an HA config will require a minimum of 3 controller nodes<br class="">
(primarily because RabbitMQ and Galera operate in odd numbered clusters)<br class="">

abeekhof is working on getting better docs on the HA stuff on our wiki<br class="">
but you can ask questions here though<br class="">
