say your logical volume path is /dev/vg00/lv01 and that LV
holds your ext2 filesystem.

tune2fs -L Whatever /dev/vg00/lv01 # labels it with volume name "Whatever"

If you have an entry in /etc/fstab like:
/dev/vg00/lv01	/mnt	ext2	defaults	1 1

running "mount -L Whatever" should do the trick.
Presumably /mnt exists and the volume group is active.
