One approach is discussed here:

https://www.redhat.com/archives/linux-lvm/2003-May/msg00013.html

There is also a portion of the LVM HOWTO that addresses converting a 
root filesystem to LVM:

http://www.faqs.org/docs/Linux-HOWTO/LVM-HOWTO.html#UpgradeRootToLVM

These documents include warnings about recovery problems.  I learned 
this the hard way a year and a half ago, when one of the four drives in 
my LVM HP-UX system died.

I was able to get the drive replaced and the system running again, but 
it was a major effort!  Someone with more LVM experience might have 
found it easier though.

Good luck,
