how is it possible to figure out what minor in parted's ouput refers to a specific lv

for example:

8 57035.487 57137.431 logical lvm
9 57137.462 57239.406 logical lvm



I resized LogVol02 :
e2fsadm -L-5 /dev/Volume00/LogVol02
then
lvextend -L +2 /dev/Volume00/LogVol00
so
i need to make these changes in the fs of LogVol00
(I think e2fsadm alrady reduced th fs for LogVol02
right?)

the problem is LogVol00=/ and cant be unmounted. Perhaps parted will allow me to resize but I cand figure out which minor is LogVol00 or /
