As a follow up to Brian's message[1] regarding Essex -> Folsom upgrades we are announcing the initial availability of Grenade[2], a test harness for performing OpenStack upgrades using DevStack. The wiki has more information at http://wiki.openstack.org/Grenade and the code is on GitHub at https://github.com/nebula/grenade. At this point we know that the upgrade steps outlined in Grenade's upgrade-* scripts are incomplete but as Brian mentioned have already uncovered some issues in database migrations. We have begun discussions with the CI team regarding an appropriate way to utilize Grenade in the CI process. Details are still being worked out but the goal is to find upgrade issues early in the development cycle rather than in the last weeks before a release. It is also another way to document/demonstrate the steps required to upgrade between releases. dt [1] http://lists.openstack.org/pipermail/openstack-dev/2012-September/001259.html [2] http://wiki.openstack.org/Grenade [3] https://github.com/nebula/grenade -- Dean Troyer dtroyer at gmail.com
