I have not tried lvm on Debian, but last time I did an lvm install on
Ubuntu, it was tricky. I could n't install it directly from the install CD.
I don't know how different Debian is from Ubuntu, but following is
what I did on Ubuntu.
1. Boot into livecd
2. Open terminal and Install the lvm package
3. Load the kernel module dm-mod via modprobe
4. Manually partition the disk using fdisk
Boot can't be part of lvm. Make sure that boot is on a separate
partition and the rest per your needs. Swap can be part of lvm
5. Let the OS know of created partitions: partprobe
6. Create /boot file system using mkfs on your first partition
7. Next create your lvm partitions (including swap)
Create lvm physical (pvcreate), group (vgcreate) and logical
8. Create file systems on your lvm partitions using mkfs
9. Now on the livecd desktop you will see a 'install' icon, click that
to start install
10. When you come to disk partitioning select manual and choose
the partitions you made for appropriate mount points
11. Continue with install until the final step
12. WARNING: DO NOT GET RID OF THE POP UP WINDOW WITH
THE FOLLOWING MESSAGE:
'Do you want to continue to use Live CD or Restart'
13. Your installed system has no lvm package installed, so you need
to do that before your restart and that may be the problem you are
experiencing. Here is what you do from a terminal:
sudo chroot /target
aptitude install lvm2
14. Reboot and it should recognize boot and recognize lvm
The install I did was couple years ago and I hope it has gotten better
