LVM is not by default configured because the lvm on the kernel
(0.9.1beta2) is broken AFAIK.

you should appy this patch to the initscripts also AFAIK

you should get the new lvm userland programas and kernel module from :

  ftp://ftp.sistina.com/pub/LVM/0.9.1_beta/

until the upgraded kernel module and programs get into the oficial kernel.

while building a RH kernel don't forget to copy your configuration to a
safe place and do a $(make mrproprer) before a $(make menuconfig) or you
could end having strange dependency problems from what is left on the
kernel-source RPM

if you follow the LVM documentation you are going to be safe, i just
happened to make it work for RH7.1beta and LVM 0.9.1beta6.

and for sure, adding a new patch to the kernel SPEC and rebuilding to get
new RPMS is a nice way to get it working.

best regards,
