Ok, it is a disk partition based pool. It appears that our parted
code is assuming 512 byte sectors as you thought. I reckon that
this change should fix it
diff --git a/src/storage/parthelper.c b/src/storage/parthelper.c

}
part = ped_disk_next_partition(disk, part);
}
but I don't have any way to test this myself
