# 1. device_config_path配置规范: action_type|ring_builder_name|region|zone|host|port|device_name|weight|increment_value|
#          action_type: 设备的操作类型,支持 add improve reduce
#    ring_builder_name: ring环的类型,可选项为 account container object
#               region: 域,必须为大于0的正整数
#                 zone: 区,必须为大于0的正整数
#                 host: 设备IP地址
#                 port: ring环对应的服务端口
#          device_name: 设备名称,如:sdb1
#               weight: 权重值,必须为大于0的正整数,当设置为0时被标记为remove设备
#      increment_value: 权重的递增值,必须为大于0的正整数,建议尽量小
#示例:
#   add|account|1|1|172.16.1.100|6002|sdb1|3000|1|
#   add|container|1|1|172.16.1.100|6001|sdb1|3000|1|
#   add|object|1|1|172.16.1.100|6000|sdb1|3000|1|
#
# 2. all_datanode_list配置规范: 存储节点IP地址.
