LVM1 problems with FC2test1/FC1

[Taylor, Forrest]

A while back I did a fresh install of FC2test1 along-side a dual-boot
FC1.  In FC1 I created some LVM1 partitions before the FC2
installation.  During the FC2 installation, I didn't format any of the
logical volumes, but I used them to mount /home et al.  In FC2, they
work fine (after I figured out I have to run lvm <command>).  I created
a new logical volume in FC2 for a new project.  However, if I boot back
into FC1, I cannot mount the logical volumes.  Doing a vgscan gives this
error:

vgscan -- reading all physical volumes (this may take a while...)
vgscan -- found inactive volume group "Volume00"
vgscan -- ERROR "pv_check_consistency_all_pv(): PE" volume group
"Volume00" is inconsistent
vgscan -- ERROR: unable to do a backup of volume group "Volume00"
vgscan -- ERROR "lvm_tab_vg_remove(): unlink" removing volume group
"Volume00" from "/etc/lvmtab"
vgscan -- "/etc/lvmtab" and "/etc/lvmtab.d" successfully created
vgscan -- WARNING: This program does not do a VGDA backup of your volume
group
 
Running vgck says that there are no volume groups.  When I boot back
into FC2, everything works fine.  I am not sure if it was a problem
before I created the logical volume, and I haven't had time to reinstall
both OSes to find out.  Does anyone have any ideas how to get LVM back
in FC1?

Thanks,

Forrest
