[openstack-dev] [nova] no more expand/contract for live upgrade?
Hi, I noticed that expand/migrate/contract was revert in https://review.openstack.org/#/c/239922/ There is a new CMD 'online_data_migrations' was introduced to Nova and some data-migration scripts have been added. So I wonder will Nova keep expand the DB schema at beginning of live upgrade like before Or Nova have some new ways to handle DB Schema change? The upgrade doc was not update for a long time http://docs.openstack.org/developer/nova/upgrade.html Thanks a lot.

Best Regards, Tan [1] will help you understand current way of doing live schema upgrades. [1] http://www.danplanet.com/blog/2015/10/07/upgrades-in-nova-database-migrations/ To be clear, that's mentioned in the (in progress) release notes for Mitaka http://docs.openstack.org/releasenotes/nova/unreleased.html#new-features "Added a nova-manage db online_data_migrations command for forcing online data migrations, which will run all registered migrations for the release, instead of there being a separate command for each logical data migration. Operators need to make sure all data is migrated before upgrading to the next release, and the new command provides a unified interface for doing it."
