The attachment didn't come through, but I can use the file that you posted
before.  The PV you have is completely used, but restoring this configuration
should get you back to a state where you can try again to extend the VG to
a new PV.  You can do _all_ of that online -- no need to resort to a live
CD.  And this time, don't remove or overwrite that new PV until you have
successfully purged it from the LVM structure.

Updated file attached as LVMconfig.new .  All I have done is comment out
two blocks of lines referring to "pv1" and change the segment count to "1"
for lv_root.  You will need to run

     vgcfgrestore -v --file LVMconfig.new vg_devserver

You might want to try it first including the "--test" option to see what
it is going to do.
