just wanted to give a short status on the work around the HA
architecture described in the SPEC here:
https://review.openstack.org/299628 (blueprint here )
The last chunk of the work is currently contained in these two reviews:
https://review.openstack.org/#/c/342650/ - cinder volume constraint move
https://review.openstack.org/#/c/314208/ - Main Tripleo Heat Templates changes
The patches are very small at this point, because after a chat with
Giulio we made sure that the initial big patches were split off in
smaller, more easily consumable bits. We also made it so that even
openstack-core is a profile that can be turned on and off. This work
still depends on the Aodh profiles  work landing in master. Once Aodh
is committed the change is rather trivial. Testing has been successful
so far. Given that it can be rolled back with a simple tweak to
environments/puppet-pacemaker.yaml we have a solid non-intrusive plan B,
should we encounter any unforeseen major issues.
For the long-term (so Ocata at least), we can work to remove all the
tripleo::profile::pacemaker classes that won't be needed any longer.
I think it makes sense to keep them around for at least one release.
I hope we can land these changes sometime this week or beginning of the
next (depending on how the aodh reviews go). In any case either Chris or
I will be around for any question/issues.
Thanks for reading so far ;)
