OpenStack Compute (nova)

No downtime DB migrations

Registered by Johannes Erdfelt

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.
