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.
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?
Thanks for your great job
