We presented this architecture on a Crowbar meetup about a month ago. Any help people wish to provide on this would be great.
As we move forward we will be sure to email to this group on our progress.

Why? If the barclamps are extended in the right way, it should not be much extra effort to deploy an architecture which uses Pacemaker.

Did I miss a big announcement somewhere? Please keep the Crowbar community updated on what you are working on with HA, since this is a critical piece, and we are very interested in this too. We have quite a bit of Pacemaker / Corosync experience in-house (e.g. we employ some of the core developers) which could be harnessed to help move this forward. Thanks a lot for publically documenting this though - the architecture looks very promising. By the way, the diagram at https://github.com/crowbar/crowbar/wiki/Openstack-High-Availability-Logical-Architecture is unreadably small. Is there a larger version available?
