based on a stock install (the only change i made was to reduce the size of the /home logical volume since i want to leave some VG room for class exercises), the default VG name is still "VolGroup", but the LV names look more reasonable -- i got /dev/VolGroup/lv_home for the LV where /home is mounted so that's *some* improvement. -- ======================================================================== Robert P.
