Hi all,

We used similar manifest about year ago.
They added HAProxy monitoring script - we added Pacemaker.

This script includes our old thin place - there is dedicated Galera master
node, and it should start new cluster on every reboot/ MySQL restart, even
if other nodes are alive.

Additionally, HAProxy balancer example in this repo distributes connections
to MySQL between the different nodes, but as I see there is the following
setting

wsrep_causal_reads=0


So, since OpenStack gets info through AMQP in parallel with MySQL, it is
possible it would request the MySQL node which still has not synchronized
the latest transaction.

Kind regards,
Miroslav
