>                 Key: HDDS-1773
>                 URL: https://issues.apache.org/jira/browse/HDDS-1773
>             Project: Hadoop Distributed Data Store
>          Issue Type: Improvement
>            Reporter: Eric Yang
>            Priority: Major
>
> Disk errors can also be simulated by setting cgroup blkio rate to 0 while Ozone cluster is running.  
> This test will be added to corruption test project and this test will only be performed if there is write access into host cgroup to control the throttle of disk IO.
> Expected result:
> When datanode becomes irresponsive due to slow io, scm must flag the node as unhealthy.
