Eric Yang created HDDS-1773:
-------------------------------
Summary: Add intermitten IO disk test to fault injection test
Key: HDDS-1773
URL: https://issues.apache.org/jira/browse/HDDS-1773
Project: Hadoop Distributed Data Store
Issue Type: Improvement
Reporter: Eric Yang
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.
