Ethan Rose updated HDDS-1773:
-----------------------------
    Target Version/s: 1.3.0  (was: 1.2.0)

I am managing the 1.2.0 release and we currently have more than 600 issues 
targeted for 1.2.0. I am moving the target field to 1.3.0.

If you are actively working on this jira and believe this should be targeted 
for the 1.2.0 release, Please reach out to me via Apache email or Slack.

> 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.
