Subject [jira] [Commented] (HDDS-1554) Create disk tests for fault injection test
Date Fri, 12 Jul 2019 00:13:00 GMT

    [ https://issues.apache.org/jira/browse/HDDS-1554?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16883425#comment-16883425
] 

Eric Yang commented on HDDS-1554:
---------------------------------

Patch 12 addressed all comments up to date.  Most of reusable code has been moved to ClusterTester
class with a set of primitive methods for reuse purpose.  [~arp] All yaml file have been clean
up to use inheritance.  

[~elek] For H) there is no fix because between cluster restart there is a 30 seconds wait
time, I think this is sufficient for initialize scm metadata, hence no extra handling has
been added.

I think I addressed all previous concerns, let me know if I miss anything.  Thanks

> The current plan for fault injection disk tests are:
>  # Scenario 1 - Read/Write test
>  ## Run docker-compose to bring up a cluster
>  ## Initialize scm and om
>  ## Upload data to Ozone cluster
>  ## Verify data is correct
>  ## Shutdown cluster
>  # Scenario 2 - Read/Only test
>  ## Repeat Scenario 1
>  ## Mount data disk as read only
>  ## Try to write data to Ozone cluster
>  ## Validate error message is correct
>  ## Shutdown cluster
>  # Scenario 3 - Corruption test
>  ## Repeat Scenario 2
>  ## Shutdown cluster
>  ## Modify data disk data
>  ## Restart cluster
>  ## Validate error message for read from corrupted data
>  ## Validate error message for write to corrupted volume
