Can you tell me what you mean by "per-disk host-managed
integrity-checking"? Are you running dm-integrity in your setup? Can
you post the output of:
lsblk
so we understand better what you have? But in any case, good luck
with getting RAID6 solid and working as a pure LVM setup. I don't
think you're going to make it happen any time soon, and I honestly
prefer to have seperate layers for my setup so that each layer does
it's own think and does it well.
John
