URL: https://github.com/apache/incubator-doris/issues/4328


   I try to simulate multi disk error on BE and I ignore "errno == EIO" 
condition at be/src/olap/utils.h 256
   Then I build one fe and one be which has multi **disk data paths** and set 
config as follow:
   ignore_broken_disk=true
   max_percentage_of_error_disk=75
   ignore_load_tablet_failure=true
   Next I create a table which has only **one replication** and I load some 
data to my table
   Finally I change mode one of disk data path to 500 so that BE couldn't 
access .testfile and disk is offline.
   After that, FE report tablet error and can't work such as query data, load 
data, restart etc.
   It doesn't happen in table with multi replication or BE with single disk 
data path.
