=== Introduction to LVM ===
+
Learn more about Funtoo Linux's development priorities at [[Funtoo Linux Vision]].
LVM (Logical Volume Management) offers a much more flexible way of managing your storage devices. Not only does it allow you to resize your volumes while the system is still up, it also frees you from having to decide exactly how many or how big volumes need to be at the time of installation.  
+
  
For a detailed tour and introduction to LVM please consult the [[LVM Fun]] page.
+
== Getting Started ==
  
 +
We encourage you to [[Funtoo Linux Installation|install Funtoo Linux]], and get involved in our user community. Get to know fellow Funtoo Linux users on our [http://forums.funtoo.org forums]. If you have any improvements or find any bugs in Funtoo Linux, you are strongly encouraged to report them on our [http://bugs.funtoo.org bug tracker]. We take all bugs seriously, and all work performed on Funtoo Linux is tracked on our bug tracker, for purposes of transparency.
  
== Live CD ==
+
Funtoo Linux has a very active [http://en.wikipedia.org/wiki/IRC IRC] community on Freenode, in the <code>#funtoo</code> channel, and you are encouraged to hang out online with us.
Please read the [[Funtoo Linux Installation#Live CD|Live CD]] section in the regular guide. The only thing you need in addition to the [[Requirements|requirements]] it mentions is the sys-fs/lvm2 package or equivalent. If you use [http://www.sysresccd.org/ System Rescue CD], it includes the lvm2 package.
+
  
== Prepare Hard Disk ==
+
== Distinctives ==
Preparing the hard disk for an LVM install isn't much different from a normal install except that we won't be creating a bunch of partitions as we are going to use logical volumes instead. All we need is a /boot partition, if your using gpt, you'll need the GRUB partition, and the rest of the space will just be one big partition which we'll create our logical volumes out of.
+
  
{{fancynote|We're using the previous mentioned setup to keep things simple in this guide. We are also assuming your only using one hard disk though LVM supports adding multiple hard disks and partitions to a volume group. Please adapt these instructions to suit your needs}}
+
Funtoo Linux is led by [http://en.wikipedia.org/wiki/Daniel_Robbins_(computer_programmer) Daniel Robbins], the creator and former Chief Architect of [http://en.wikipedia.org/wiki/Gentoo_Linux Gentoo Linux], who serves as benevolent dictator for life (BDFL) of the project. Our organizational structure consists of BDFL and a small number of support staff, as well as members of our user community who are involved in improving Funtoo Linux. Developement efforts are driven by the BDFL as well as our users, and efforts are under way to implement various mechanisms to allow supporters of Funtoo Linux to chart the future direction of the project.
  
The regular install guide does a good job explaining MRB, GPT, and gdisk/fdisk so we won't be repeating that here. Read through the [[Funtoo Linux Installation#Prepare Hard Disk|Prepare Hard Disk]] section and create the previous mentioned partitions.  
+
Funtoo Linux packages are installed from source code, automatically, thanks to the [http://en.wikipedia.org/wiki/Portage_(software) Portage ports system.] Funtoo Linux has its own distinct ports tree (repository of packages), which is based on Gentoo's. Every several hours, the Funtoo Linux Portage tree is updated using an automated merge process, to include the latest changes from Gentoo Linux, Funtoo Linux developers and contributors, as well as other independent developers.  
If your following our setup your partition table should look like the following when completed:
+
  
'''GPT partition table'''
+
We use [http://en.wikipedia.org/wiki/Git_(software) Git] for all our development, and we also use Git to deliver our Portage tree to you.

== Creating Logical Volumes ==
+
'''Add an Ebuild page:''' (see [[Adding an Ebuild to the Wiki]] for instructions)
In this section we will cover the basics of creating volume groups and logical volumes. For an in depth explanation please see the [[LVM Fun]] page.
+
  
=== Creating a Physical Volume ===
+
{{#forminput:form=Ebuild|size=|default value=|button text=Add Package|autocomplete on namespace=Package|remote autocompletion|placeholder=Descriptive name|popup}}
Our first step is to create a physical volume which basically just tells the lvm where to write the data to.
+
Create a physical volume out of the big partition we created in the previous step. If your using the MRB setup then change /dev/sda3 to /dev/sda2 in the following command
+
<console># pvcreate /dev/sda3</console>
+
  
=== Creating a Volume Group ===
+
__NOTITLE__
Now that we have a place to store our data we need to create a volume group for it. A volume group is simply a named group of at least one physical volume. This allows multiple physical volumes to be used to store data. In our simple example we only have one physical volume so we'll create a volume group and add our physical volume to it in one command. We are going to call our volume group "vg" but you can name it anything you want. Remember to adjust the device path if your using MRB.
+
__NOEDITSECTION__
<console># vgcreate vg /dev/sda3</console>
+
 
+
=== Creating Logical Volumes ===
+
We now come to the heart of using LVM, logical volumes. Here we get to create logical volumes to store our data. Remember that the best part of LVM is the ability to resize volumes later on the fly so keep that in mind when deciding how big to make volumes. No need to allocate all your space right away. Also keep in mind when choosing a file system type that it must support resizing in order to take advantage of LVM's resizing features.
+
For our simple example we are only going to create 3 logical volumes and use them for /(root), /home, and /tmp.
+
Create the root volume:
+
<console># lvcreate --size 10G --name root vg
+
Logical volume "root" created</console>
+
As you can see we use the --size option to specify a 10 gig volume and the --name option to name the volume 'root'. Again , you can call your volumes anything you want just remember to adjust the paths in the commands for the rest of the guide. You'll notice we specified a relatively small root partition. This is due to our test disk only being 40G. The last item in the command is simply the name of the volume group we created in the previous section. Run 'lvcreate --help' or consult the manpages for more information on the options use.
+
 
+
Now lets create the other 2 logical volumes for our example:
+
<console># lvcreate --size 5G --name tmp vg
+
Logical volume "tmp" created
+
#lvcreate --size 10G --name home vg
+
Logical volume "home" created</console>
+
 
+
== Creating filesystems ==
+
{{fancynote|Before proceeding you should read through the brief section [[Funtoo Linux Installation#Creating filesystems|Creating filesystems]] in the install guide and decide what type of filesystem you would like to use. Do not actually create any file systems though, we will cover that below.}}
