I've sent a patch that will show actual redundancy like following:

    dog: show actual redundancy scheme for 'vdi list'
    
    With this patch, 'vdi list' will show actual redundancy as follow:
    
    yliu at ubuntu-precise:~/sheepdog$ dog/dog vdi list
      Name        Id    Size    Used  Shared    Creation time   VDI id  Copies  Tag
      test         0   10 MB  0.0 MB  0.0 MB 2014-01-21 15:54   7c2b25    4:2
      test1        0   20 MB  0.0 MB  0.0 MB 2014-01-21 15:59   fd32fc      3
