Just take notice that sequencial logical volume (partition) may be not
sequencial on the physical volume (There's a logical extent to physical
extent mapping).

However, there is a good chance most/all of your partition is
sequencial, especially if you created the volume group and the logical
volumes when the disk was empty (e.g: during installation) without
requiring a striped logical volume (it's not the default).

Good luck,
