What I meant is following case:

3 nodes with 3 copies:

0       1      2     3
+       -      -     + <-- lost the updates.
+  -->  + -->  - --> #
+       +      -     # <-- permanently down.
        ^
        |
     These two nodes has the latest data.

Even with quorum, we can't handle this case.

Thanks,
Yuan
