Arpit Agarwal commented on HDDS-1554:
-------------------------------------
Looking at the test case implementations:
# {{ITDiskReadOnly#testReadOnlyDiskStartup}} - The following block of code from
can be removed, since it's really testing that the cluster is read-only in safe
mode. We have unit tests for that:
{code}
try {
createVolumeAndBucket();
} catch (Exception e) {
LOG.info("Bucket creation failed for read-only disk: ", e);
Assert.assertTrue("Cluster is still in safe mode.", safeMode);
}
{code}
# {{ITDiskReadOnly#testUpload}} - do we need to wait for safe mode exit after
restarting the cluster? Also I think this test is essentially the same as the
previous one. Once we have ensured that read-only disk forces us to remain in
safe mode, the rest of the checks should be covered by safe-mode unit tests.
Still reviewing the rest.

> 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
