Hi,
After I install the devstack,
http://docs.openstack.org/developer/devstack/guides/multinode-lab.html (http://docs.openstack.org/developer/d...)
I try to install bare metal service.
http://docs.openstack.org/developer/ironic/deploy/install-guide.html (http://docs.openstack.org/developer/i...)

When I create the database tables, it shows error:

root@myhost:~# ironic-dbsync --config-file /path/to/ironic.conf create_schema
usage: ironic-dbsync [-h] [--config-dir DIR] [--config-file PATH] [--debug]

[--log-date-format DATE_FORMAT] [--log-dir LOG_DIR]
[--log-file PATH] [--log-format FORMAT] [--nodebug]

{upgrade,downgrade,stamp,revision,version} ...
ironic-dbsync: error: argument command: invalid choice: 'create_schema' (choose from 'upgrade', 'downgrade', 'stamp', 'revision', 'version')

Here is my ironic-dbsync version:
root@myhost:~# ironic-dbsync --version
2014.1.rc1
