Thank you for clarifying it sir. Then for `-l 8` I expect all
`lvolX_rimage_N`s has 4 extents rather than 8:
--- Segments ---
Logical extents 0 to 7:
Type raid10
Monitoring monitored
Raid Data LV 0
Logical volume lvol5_rimage_0
Logical extents 0 to 7
Raid Data LV 1
Logical volume lvol5_rimage_1
Logical extents 0 to 7
...

The default LE size was 4MiB, so that I expect lvol1 to be 2*4*24576
MiB, while other 4 are all 2*4*8 MiB. However, I only got 4*24576 MiB
and 4*8 MiB partitions. I tried to run `mkfs.ext4` on lvol3 and mount
it. `df` shows clearly that lvol3 is a 32MiB volume.
The -l option is the final size of the LV, not the space used on each device
for each stripe or mirror. So when you say -l 8, it means the LV has 8
usable extents, so it is supposed to be 32MiB. It doesn't matter how many
stripes or mirrors you have.
