I have a RAID-10 setup of four 400 GB HDDs. As the data grows by several

Which would be easy, if I didn't have to do it online, without stopping
any services.
Your /dev/md10 - what is directly on top of it? LVM? XFS? EXT3?
Good point. I don't want to copy the whole RAID-10.
I want to copy only one LVM-2 volume (which is like 90% of that RAID-10,
anyway).
So I want to synchronize /dev/LVM2/my-volume (ext3) with /dev/sdr (now
empty; bigger than /dev/LVM2/my-volume).
(sda2, sdb2, sdc2, sdd2) -> RAID-10 -> LVM-2 -> my volume -> ext3
