About LVM on Ubuntu 12.04

Specs: Linux x86_64, AMD Phenom II 4X
Hi all,

I newly installed Ubuntu 12.04.1 from ubuntu-12.04.1-desktop-amd64.iso

Installation went through without problem but without LVM. Ubuntu is now up running.

I ran following command trying to mount LVM but failed;

# apt-get install lvm2
# vgchange -ay
No volume groups found


Please help.

Which ISO should I use to install LVM? ubuntu-12.04.1-alternate-amd64.iso ?

TIA

B.R.

I don't quite understand what you are expecting. If you installed without using an LVM setup then, of course, there won't be any volume groups defined. You can create them now on spare partitions/disks, but your install partition will still be a normal one, not an LVM one.

If you want a fully LVM managed system then you need to install it as such. Fedora lets you do this, but I don't know about Ubuntu. TBH, unless you have multiple isks LVM is more trouble than it is worth IMO.

It might be the OP is confusing LVM as in package with LVM as in a disk managment scheme?

Agreed. "Installation went through without problem but without LVM."

Not even sure you needed to apt-get install lvm* All that should have been there by default. You normally should not be on root logon so sudo would have been needed.

The best way would have been to get latest iso of your choice. Then when you partition it, select the LVM as choice for partitions.
