> # Start two DN's  (DN1,DN2).
>  # Write fileA with rep=2 ( dn't close)
>  # Stop DN1.
>  # Write some data to fileA.
>  # restart the DN1
>  # Get the blocklocations of fileA.
> Here RWR state block will be reported on DN restart and added to locations.
> IMO,RWR blocks which having less GS shouldn't added, as they give false postive (anyway
read can be failed as it's genstamp is less)
