1. Install Kubuntu Feisty (7.04) Alternate Install: F6-F6-Expert Mode
2. Install LVM during initial setup
3. Boot into KDE from HD

If you need to install LVM after having setup the base system, note that there is a bug in Edgy and Feisty where the executable files will not be found. To fix it, execute the 2nd instruction below:

apt-get install lvm2
ln -s /lib/lvm-200 /lib/lvm-0

If something goes wrong during initial install or if you later need to modify / check the lvm installation, here are the relevant commands. Before setting up the lvm volumes, you might want to check the partition table (see next paragraph).

1. lvm > pvcreate /dev/sda3
2. lvm > pvcreate /dev/sdb1
3. lvm > vgcreate vg_data /dev/sda3
4. lvm > vgextend vg_data /dev/sdb1
5. lvm > vgdisplay vg_data ## check volume group, count of free extents
6. lvm > lvcreate -lxxx vg_data ## -lxxx is number of extents
7. lvm > lvcreate vg_data
8. lvm > lvrename vg_data lvol0 lv_data
9. lvm > lvdisplay vg_data # check logical volume(s)
10. lvm > vgcfgbackup to backup volume group configurations
11. lvm > exit
12. umount /srv
13. mkfs -t ext3 /dev/vg_data/lv_data
14. mkdir /srv
15. mount /dev/vg_data/lv_data /srv

to check wether the partition table is ok:

sfdisk -l

to check wether root and swap are mounted, enter:

mount
free -m -t

to check mismatching uuid's, enter:

ls -la /dev/disk/by-uuid
cat /etc/fstab

to fix, do:

vim /etc/fstab

replace the uuid's found in fstab with the ones found in /dev/disk. Make sure you copy the correct uuid (/, swap) to the respective entry in fstab.
