>       addToInvalidates(b.corrupted, dn); 
>       removeStoredBlock(b.stored, node);
> {code}
> We don't delete corrupted block if all we left is corrupted block. We give user the decision. So user has chance to recover it manually.
> We should not compare liveReplicas() of Striped block with "1". The logic need update.
