在crystal页面上往存储策略中添加设备后，查看builder文件报错，报错信息如下：

Traceback (most recent call last):
  File "/usr/bin/swift-ring-builder", line 24, in <module>
    sys.exit(main())
  File "/usr/lib/python2.7/site-packages/swift/cli/ringbuilder.py", line 1483, in main
    getattr(Commands, command, Commands.unknown)()

在添加设备时，如果在crystal的页面中添加的region和zone是英文的话，也会出现报错
