... all the talk about this stuff, and yet noone's talked about how ZFS is supposed to be append only, and boy wouldn't that be awesome. :) So - is anyone planning on working on the minimum set of stuff to expose the write topology for these shingled disks, so experiments can start being made? Even just knowing the shingle size(s) for writes would be enough to do useful amounts of work from userspace. -adrian
