Eric Yang commented on HDDS-1554:
---------------------------------
Patch 002 setup docker compose cluster to be a distributed cluster with three
datanodes, and add corruptions to /data/metadata directory. The test case will
attempt to upload file to ozone after ozone manager database has been
corrupted. The tests will try to capture IOException to ensure that file
operation fails. At this stage, Ozone does not check metadata is corrupted,
and continue to run with in memory data. Hence, the test cases are supposed to
fail for now until more intelligence are added to Ozone to detect disk faults.

> 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
