Description of problem:

[Motivation] & [Background]

Red Hat will provide high availability the OpenStack architecture.[1]
On top of this architecture, there is clustered database using:

 MariaDB [2]
 Galera [3]

Galera configures MariaDB as cluster. [4]

This architecture provides the customers with really really high availability:
Let's say The cluster on the cluster

This solution is pretty good regarding to:


Both of them are very important factors for the customers.
But there is one important weak point.


They are quite good enough complex for the customers to operate.
Especially in case of disaster, they have *no* idea what's going on behind the clustered system.

To fix negativeness, Red Hat has to provide them with reasonable and understandable guide.

Since we will *not* be on the way to provide single node, *zero* redundant architecture in the future, it's going to be more important for us to make good progress and get much more trust from every single customer with OSP(> 7).

Please consider making a guide for MariaDB Galera cluster running on top of the Pacemaker.
I will be willing to help you make it successful.
