How reproducible: Nearly all the time, given the vms are slow enough.

There is a race condition between puppet that want to get mysql
information and the galera cluster being ready behind the haproxy.

The galera cluster show up to late (configured by pacemaker) making
the puppet run at step 2 fails.
