Well, the VG is spread over two PVs:

mondschein:~> pvs
  PV         VG         Fmt  Attr PSize  PFree  
  /dev/sda2  mondschein lvm2 a--   9,77g 784,00m
  /dev/sdb2  mondschein lvm2 a--  49,75g  19,75g

Yet the volume is only on one:

mondschein:~> lvdisplay --maps /dev/mondschein/debian 
  --- Logical volume ---
  LV Path                /dev/mondschein/debian
  LV Name                debian
  VG Name                mondschein
  LV UUID                t0GGvj-OZvH-LfvT-14Rm-THYn-tNhI-NNc3mC
  LV Write Access        read/write
  LV Creation host, time , 
  LV Status              available
  # open                 1
  LV Size                3,00 GiB
  Current LE             768
  Segments               2
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           254:0
   
  --- Segments ---
  Logical extent 0 to 511:
    Type                linear
    Physical volume     /dev/sda2
    Physical extents    0 to 511
   
  Logical extent 512 to 767:
    Type                linear
    Physical volume     /dev/sda2
    Physical extents    1018 to 1273

As I understand bug #735935 is when LV is found twice. Well I think it is 
only reachable via one path.

Thanks,
