[Bug 1804652] [NEW] nova.db.sqlalchemy.migration.db_version is racy
Public bug reported:
db_version() attempts to initialise versioning if the db is not
versioned. However, it doesn't consider concurrency, so we can get
errors if multiple watchers try to get the db version before the db is
initialised. We are seeing this in practise during tripleo deployments
in a script which waits on multiple controller nodes for db sync to
complete.
