I remember some discussion about alignment for 1.1 and 1.2: is it 
possible on 1.2 to guarantee alignment of RAID device on the physical 
devices?
4K alignment would be needed on SSDs and 2TB disks w/ 4k physical 
512b logical emulation. Actually on SSDs the alignment could be even 
more than 4k, I am not sure.

is there any problems with this commit?

Oh it IS aligned then

Should we bypass the defaults and put 1.0 metadata on those?
What was the downside of 1.0 so that it was not made default?

this has been discussed to boredom

I'm sorry
