Report a bug?

Hyphens are permitted *inside* VG and LV names, but not as the first
character.  There are also some reserved names you cannot use
because of existing /dev entries.  (E.g. a VG name of 'null' would clash
with '/dev/null' and '.' and '..' are also banned of course).

VG/LV:
  a-zA-Z0-9+_.-

(PV names are simply filenames)
