i'm unsure as to what it's trying to load a file from /lib, but i can
only guess it's looking for the lvm kernel module.

i know that mandrake ship an LVM enabled kernel, but maybe redhat dont?
i dont use redhat, so i cant say eaitehr way.  but if in doubt of such
things, it's always worth compiling your own.  get a recent kernel
source tree, and get the latest LVM 1.0.3 ( at present ).  IIRC when you
run make in the patches directory, it checks to see what patches have
already been applied to /usr/src/linux.  and then whatever's new and
needs to be included get's built into a custom patch.  which you then
apply to the source tree.

oh, and make sure you enable the kernel option for LVM support when you
recompile.

i've had a few problems getting LVM to work, and on the whole, if i'd
started with a clean kernel, + lvm patch, and LVM userspace tools it'd
have been a lot easier.

HTH,
