Description RHOS Integration 2013-12-12 15:37:11 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/no-downtime-db-migrations.

Description:

Some migrations can take a long time to finish, causing a service to be down for an unacceptable amount of time. The proposed solution is to switch to an expand, migrate, contract model where migrations occur while the services are running.

Since you can't have two blueprints with the same specification URL (already have a Glance blueprint registered):
