There is no way to do an in-place convert from a partitioned device to
LVM without losing data. I would recommend adding a new disk, reinstall
the OS on the new disk with LVM, and then moving over any data that was
required after installation.
You may be able to do this in rescue mode within a chrooted environment,
but things could get messy. Add the new device, build the lvm stack,
copy over the data then chroot into the NEW lvm root. Mount everything
appropriately, recreate the initrd and re-install grub onto the new
disk. Go in with the expectation that you may be fixing things after
the reboot from rescue mode.

Hi all.
I have red hat 5.7 with no lvm2 installed. Now I want to configure
lvm2 on the root and swap partition then later on adding a couple of
LUNs to create a VG
What's the best practice/procedure to install lvm2 on the boot disk?
Is it possible? I guess I have to run Linux CD in rescue mode
