You don't. A partition of type 0x8e typically has one PV in it. The PV
belongs to a VG. A VG has one or more LVs in it. The LVs are roughly
equivalent to ordinary disk partitions; you make filesystems within the LVs.
You can run e2label or tune*fs on an LV. When I did this for a multiboot
64/32-bit system, I had LVs named /dev/vg/usr32 and /dev/vg/usr64. Their
ext3 labels were "usr32" and "usr64", even though I never mounted by label.

...then you have situations like installing CentOS 3 and CentOS 4 to different
disks on the same system without changing the installer's defaults. So you
have 2 filesystems with LABEL="root" (or something) and stupidity ensues. I
haven't done this but people on comp.os.linux.misc have. (This means that at
some point, they'll move from mount-by-label to mount-by-UUID, and that'll be
fairly icky and incomprehensible.)
