Copy entire contents of your root filesystem onto a backup device,
(preferrably while booted from a rescue disk so the root fs is not
in use). Then re-create your root filesystem without LVM, finally 
copy everything back onto it. Pretty slow & tedious really :-( And 
besides, LVM is great - hell I even put swap onto LVM these days !
