> fsck, dfsadmin -report, and NN WebUI should report number of blocks that have
> 1 replica. We have had many cases opened in which a customer has lost a disk
> or a DN losing files/blocks due to the fact that they had blocks with only 1
> replica. We need to make the customer better aware of this situation and that
> they should take action.
