No-one ever replied as to why blockdev --setra / --getra is not the same as that displayed in lvdisplay
And it's not documented that I can find. There's a comment: "Not used by device-mapper." And that means.....?
Any LVM read ahead setting is ignored by LVM2 i.e. not passed to the kernel.
If it's demonstrated to be useful it could still be implemented, but
the current development priorities are still correctness and new features rather than performance.

It would be good to modify the docs to be clearer and maybe say "use blockdev --setra"
