jiangshouzhuang opened a new issue #1608: Backend's disks statistics (UsedPct and MaxDiskUsedPct) is incorrect
URL: https://github.com/apache/incubator-doris/issues/1608
 
 
   **Describe the bug**
   
   When executing the command "show backends; "，the UsedPct metric is found to have a negative value, such as -148.01 %, while the MaxDiskUsedPct value is 0.00%.
   
   **To Reproduce**
   1. Install FE and BE software
   2. Configure FE(conf/fe.conf) and BE(conf/be.conf)
   a parameter of the configuration file, conf/be.conf:
   ```
   storage_root_path = /disk/disk1/doris, 500;/disk/disk2/doris, 500;/disk/disk3/doris, 500;
   or
   storage_root_path=/doris/be/palo-data
   ```
   3. start FE nodes
   4. add BE nodes
   5. start BE nodes
   6. execute the command "show backends; "
   
   **Expected behavior**
   The correct result should be:
   * UsedPct: shows the utilization of the entire disk of the current backend node
   * MaxDiskUsedPct: shows the highest disk utilization of the current backend node
