I have only 1-node cluster, so I am not able to verify it when replication
factor is bigger than 1.

I run the fsck on a file that consists of 3 blocks, and 1 block has a
corrupt replica. fsck told that the system is HEALTHY.

When I restarted the DN, then the block scanner (BlockPoolSliceScanner)
started and it detected a corrupted replica. Then I run fsck again on that
file, and it told me that the system is CORRUPT.

If you have a small (and non-production) cluster, can you restart your
datandoes and run fsck again?
