User Stories: + + Frank wants to setup various of the OpenStack components in HA. He + currently can do it for MySQL and RabbitMQ, however, he's being unable + to do it for other components such as Glance and Keystone. By deploying + Ubuntu 12.10, he will find himself with the ability to be able to setup + HA for Glance and Keystone given the provided RA's are now in the + archives. + Assumptions: + These RA's are officially released by upstream (Hastexo). + These RA's are included in the resource-agents package. + Test Plans: + + 1) Upgrade path + Upgrading from 12.04 will provide the new RA's. However, in this will require manual configuration in order to provide the HA feature. + + 2) New Install + New install will require the user to configure the services in HA too.
