   **Problem**
   * diskMaxUsedSpaceRatio had no effect.
   * with error below
   ```
   org.apache.rocketmq.client.exception.MQBrokerException: CODE: 14 DESC: service not available now. It may be caused by one of the following reasons: the broker's disk is full [CL: 0.92 CQ: 0.92 INDEX: 0.92], messages are put to the slave, message store has been shut down
   ```
   
   **How to solve**
   * With -Drocketmq.broker.diskSpaceWarningLevelRatio instead of diskMaxUsedSpaceRatio
   
   **New Question**
   Finally, solved this problem after delving in source code.
   In fact ,the parameter `diskMaxUsedSpaceRatio ` does not work, it can be solved by parameter `diskSpaceWarningLevelRatio` with -Drocketmq.broker.diskSpaceWarningLevelRatio
   
   As the snippet below,the `diskMaxUsedSpaceRatio` seems to have no effect,Is it possible to be optimized here?
