I was rather expecting maybe 5 lines, all within a 1MiB range. I'm pretty sure, but not absolutely sure, that LVM metadata is in the first 1MiB. And yet in your first 1MiB that was supposedly zero'd, there's a bogus GPT (header only), and a btrfs signature, and that doesn't pass the smell test. Something is missing about our understanding of how all of this is supposed to be assembled. I'll have to think about the proper questions to even ask next. -- Chris Murphy
