You specified a PV, not a VG.  Try:
# vgs vg01


Here's what it does on my system:

# vgs
   WARNING: Ignoring duplicate config node: filter (seeking filter)
   VG           #PV #LV #SN Attr   VSize VFree
   main_huge_vg   9   1   0 wz--n- 2.69T    0

# vgs main_huge_vg

   VG           #PV #LV #SN Attr   VSize VFree
   main_huge_vg   9   1   0 wz--n- 2.69T    0
