Problem with LVM2

[Robin Atwood]

I have just been installing Grub2. All went well until I ran the mkconfig: 
 

 # grub2-mkconfig -o /boot/grub2/grub.cfg 
 Generating grub.cfg ... 
 /usr/sbin/grub2-probe: warning: Couldn't find physical volume `pv1'. Some 
modules may be missing from core image.. 
 /usr/sbin/grub2-probe: warning: Couldn't find physical volume `pv1'. Some 
modules may be missing from core image.. 
 /usr/sbin/grub2-probe: warning: Couldn't find physical volume `pv1'. Some 
modules may be missing from core image..

I have no volume pv1: 
 
   # pvs 
   PV         VG   Fmt  Attr PSize   PFree 
   /dev/sda3  vg00 lvm2 a--  213.79g 59.79g 
   /dev/sdb4  vg00 lvm2 a--  170.73g 84.73g 
 
   
The generated grub.cfg looks OK, AFAICT. So is this a serious problem? 
 
TIA
