      I just noticed that sometimes lfs mirror extend -N creates new objects on used OSTs:

      # lfs setstripe -c2 $tf
# lfs mirror extend -N $tf
# lfs getstripe -v $tf | grep l_ost_idx
      -   0: { l_ost_idx:   0, l_fid: [0x240000400:0x2:0x0] }
      -   1: { l_ost_idx:   1, l_fid: [0x280000400:0x2:0x0] }
      -   0: { l_ost_idx:   3, l_fid: [0x300000400:0x3:0x0] }
      -   1: { l_ost_idx:   0, l_fid: [0x240000400:0x3:0x0] }

      all OSTs are fresh, just formatted
