4. Would it be possible to later '--grow' the array to use 4 discs in
   raid10 ? Even with far=2 ?

    

No.

Well.... if by "later" you mean "in five years", then maybe.  But the
code doesn't currently exist.
  

That's a reason to avoid raid10 for certain applications, then, and go 
with a more manual 1+0 or similar.

Not really.  You cannot reshape a raid0 either.

Can you create a raid10 with one drive "missing" and add it later? I 
know, I should try it when I get a machine free... but I'm being lazy today.

Yes, but then the array would be degraded and a single failure could
destroy your data.
