Installation problem on LVM

[satimis]

Hi all,

Ubuntu 12.04 desktop 64 bit

Performed following steps to reinstall Ubuntu

1)
Download "ubuntu-12.04.1-alternate-amd64.iso" and burned it on USB drive/stick

2)
Booted up the PC with the said drive/stick. Deleted old partitions and created new partitions with LVM /root. Installation went through without problem

3)
Started Ubuntun 12.04 desktop. Ran "sudo apt-get update && sudo apt-get upgrade

4)
On terminal

$ sudo fdisk -l

$ sudo apt-get install lvm2

$ sudo vgchange -a y

  No volume groups found

Pls help. TIA

So, type
mount
to show where your file systems are mounted.

To see your volume groups, type
vgscan

To see your lv's, type
lvscan

I followed;
HowTo: Setup Ubuntu Desktop with LVM Partitions
https://help.ubuntu.com/community/UbuntuDesktopLVM

to install Ubuntu. But it didn't start two options of "Try Ubuntu" and "Install Ubuntu"

Then I continued the installation without manual and came to the result as posted previously. Ubuntu was installed in about half space of the HD leaving the rest space for another Linux OS.

I made another round installing Ubuntu on the complete space of the HD. Then I was allowed to create LVM.

$ sudo fdisk -l

Disk /dev/mapper/lvm-swap_1 doesn't contain a valid partition table

But still there is problem on "Disk /dev/mapper/lvm-root doesn't contain a valid partition table"

I think I have to use "ubuntu-12.04.1-desktop-amd64.iso" NOT "ubuntu-12.04.1-alternate-amd64.iso" The former would start two options of "Try Ubuntu" and "Install Ubuntu"

That is normal. It's not a problem.

Is there an issue you're having with the actual operation of the system?

No. What I need is to install a dual boot system, Ubuntu and Fedora.

My target is testing Cloud, OpenStack and oVirt. Ubuntu for testing OpenStack and Fedora for oVirt. It took me couple days on installing these 2 systems

There is nothing wrong with Alternate installation image. It has text based installer and it doesn't give Live mode option.

Didn't you select LVM in Partition Section during installation? All installers give an option to manage partitions before install starts.

From my recollection:
- I can't create LVM partitions first. Because I can't assign /root on it.
- Nor can I partition the HD first to install Ubuntu. I have to create Logical Volume Group first from there installing Ubuntu to take up the complete HD

Another problem of unknown cause is;

Root password didn't work after installation. I have to start "recovery" mode and dropped to root shell to run;

# mount -rw -o remount /
# passwd root

I use the same root password through out all OS under testing for years.

Another problem surfaces on installing Fedora 17 as dual boot. There is no spare space.

see photo attached.

Neither I can resize Ubuntu with the device provided by the installer.

I have to follow the steps on;
Dualboot on lvm with luks
fedora - Dualboot on lvm with luks - Super User

Is there an easy way? Otherwise I prefer going back to physical partitioning without LVM

TIA
