cinder-manage <category> <action> [<args>]


cinder-manage provides control of cinder database migration, and provides an interface to get information about the current state of cinder. More information about OpenStack Cinder is available at OpenStack Cinder.


The standard pattern for executing a cinder-manage command is: cinder-manage <category> <command> [<args>]

For example, to obtain a list of the cinder services currently running: cinder-manage service list

Run without arguments to see a list of available command categories: cinder-manage

Categories are shell, logs, migrate, db, volume, host, service, backup, version, and config. Detailed descriptions are below.

You can also run with a category argument such as ‘db’ to see a list of all commands in that category: cinder-manage db

These sections describe the available categories and arguments for cinder-manage.
