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?
