Hello, guys,
I'm trying to build an raid10 lv for root fs. I used these commands:
lvcreate --type raid10 -m 1 -i 2 -l 24576 pve # created lvol1
lvcreate --type raid10 -m 1 -i 2 -l 8 pve # created lvol2
lvcreate --type raid10 -m 1 -i 2 -l 8 pve # created lvol3
lvcreate --type raid10 -m 1 -i 2 -l 8 pve # created lvol4
lvcreate --type raid10 -m 1 -l 8 pve # created lvol5
Last two commands was runned in rescue mode of openSuSE Leap 15.0, with
a slightly newer lvm version (about 2017-09-xx). While first 3 commands
was runned in Proxmox VE 5.2, whoes lvm is 2.02.168(2016-11-30).
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.
Output of `lvdisplay -m`is as follow. Note that all lvol1-5 has a
"Mirrored volumes" value of 4. I suppose that this value should be 2 for
a 4-PV RAID10 setup.Any suggestions?

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.

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
...

I believe that those are the logical extents that are involved in those
stripes. All of the logical extents will store some data in each of the
slices.
Try "lvs -a" to see the actual space on disk used by each of the segments.
