Browse Source 
Also, leave out the note about "circular buffer" which is
an internal imeplementation detail anyway and not quite
informational for users:

Before this patch:
$ vgcreate vg1 /dev/sda
  VG vg1 metadata too large for circular buffer
  Failed to write VG vg1.

With this patch applied:
$ vgcreate vg1 /dev/sda

  Failed to write VG vg1.
