Nakshatra Linux in a LVM (Logical Volume Manager) Setup
================================================

To get started we recommended using one disk as a starting point 
to install Nakshatra linux in LVM setup, and then add subsequent 
disks later.
After logging in as root, use cfdisk or fdisk to create the necessary 
LVM structures. 
You will have to run fdisk or cfdisk first to create the partition(s) you 
want to use for setting up the logical volumes. 
For any partition you create and that you want to use for LVM, you 
should set the partition typeto '8e' (Linux LVM).


Run the following sequence of commands in for setup to install the 
OS.

1. create a pv
2. create a vg
3. create the lv(s) of desired size.
4. create a swap partition and then enable it using mkswap 
5. run setup

Preparing the Physical volumes
---------------------------------------------
For example, Let's assume we have a 30GB partition /dev/sda1 of type LVM.
Then run , 

# pvcreate /dev/sda1 

This will create a physical volume of 30GB.
Next we create a volume group or vg.

# vgcreate rootvg /dev/sda1 

This will create a root volume group called rootvg containing the 
physical volume or pv  /dev/sda1.

Next we create a LV or logical volume.

========================================================

A word about using a Logical Volume for SWAP
--------------------------------------------------------------
How to create a swap logical volume

  # lvcreate -L 1G -n swap rootvg 

	where -L = size of the lv
		   -n = name of the lv

This will create a logical volume called "swap" in the root volume group.

Now , enable it using the mkswap command.

  # mkswap /dev/rootvg/swap

==========================================================


# lvcreate -L 15G -n rootlv rootvg 

This will allocate 15GB of space for the root logical volume 
for setup to install to. 
You can choose your desired lv size accordingly and 
additional Logical volumes can be created as per requirements.

eg: # lvcreate -L 5G -n home rootvg

The setup wizard / installer will automatically recognize and activate any 
pre-existing Logical Volumes on your hard drive(s).  

These Logical Volumes will be selectable targets for the creation of the 
filesystems (like /, /usr, /home, /var) etc 

If you want, you can just allocate all remaining space inside the
Volume Group to a Logical Volume.  Suppose we want to allocate 
all available space to our 'home' LV, then this will the command to 
use

# lvcreate -l 100%FREE -n home rootvg

========================================================

The device nodes for the logical volumes are created, and the volumes
will be activated automatically when running lvcreate.

You can now run setup.
