Not at all OT. We started using parted when we started using 3TB drives a

Wait, you're resizing a partition? I don't know if I'd want to do that
with data there, unless you were *SURE* there was nothing in that area.
For future reference, when I partition a disk, I start parted with -a opt,
to make sure it knows in advance that I want optimal alignment, then, as
an example, if I'm partitioning a large drive, I do this:
mklabel gpt
mkpart pri xfs 0.0GB 100%
and it's aligned properly. I discovered some time back that using the
x.0GB syntax got parted to align it correctly, and it doesn't complain.
