In case of the RAID10 5GiB thing I think I was mixing up things. When
doing mkfs you end up with a RAID10 chunk of 5GiB (dunno why, didn't
research), when mounting and pointing balance at it, I get a 10GiB for
it back, so that's ok.
For the DUP thing, I sent an explanation ("DUP dev_extent might overlap
something next to it"), which doesn't seem to attract much attention
yet. I'm preparing a pile of patches to volumes.[ch] to fix this, clean
up things that I ran into and make the logic a bit less convoluted.
