Yes I know it should work.
# vgs vg01
VG #PV #LV #SN Attr VSize VFree
vg01 1 0 0 wz--n- 3.82G 3.82G
The point I want to say is, vgs command _should_ return non-zero
exit status value, if vgs command returned an error.
Reference: man lvm(8)
DIAGNOSTICS
All tools return a status code of zero on success or non-zero on fail-
ure.
