MySQL is available after full restart of environment
----------------------------------------------------

Older versions of Galera
(which manages MySQL in an OpenStack environment)
sometimes failed if the Controllers in an HA environment
come back online in a different order than Galera expected.
Release 5.1 includes a new RA (resource agent)
for Galera and Pacemaker
that supports a cluster bootstrap
that can reboot the whole cluster or any node in the cluster.
It uses Galera GTID (Global Transaction ID)
to determine which node has the latest database version
and uses this node as the Galera PC (Primary Component).
The administrator can manually choose a different node
to serve as the PC.
This fixes this issue.
