cinder-manage¶

Cinder Db¶

cinder-manage db version

Print the current database version.

cinder-manage db sync [--bump-versions] [version]

Sync the database up to the most recent version. This is the standard way to create the db as well.

This command interprets the following options when it is invoked:

version Database version

—bump-versions Update RPC and Objects versions when doing offline upgrades, with this we no longer need to restart the services twice after the upgrade to prevent ServiceTooOld exceptions.

cinder-manage db purge [<number of days>]

Purge database entries that are marked as deleted, that are older than the number of days specified.

cinder-manage db online_data_migrations [--max-count <n>]

Perform online data migrations for database upgrade between releases in batches.

This command interprets the following options when it is invoked:

—max-count Maximum number of objects to migrate. If not specified, all possible migrations will be completed, in batches of 50 at a time.

Returns exit status 0 if no (further) updates are possible, 1 if the --max-count option was used and some updates were completed successfully (even if others generated errors), 2 if some updates generated errors and no other migrations were able to take effect in the last batch attempted, or 127 if invalid input is provided (e.g. non-numeric max-count).

This command should be run after upgrading the database schema. If it exits with partial updates (exit status 1) it should be called again, even if some updates initially generated errors, because some updates may depend on others having completed. If it exits with status 2, intervention is required to resolve the issue causing remaining updates to fail. It should be considered successfully completed only when the exit status is 0.
