Set Up LVM/LVM2 Using Webmin

First off, what is Logical Volume Management and why do you need it? LVM is basically a set of hard drives grouped into being seen by the system as one hard drive. It is different than RAID, because there is no redundancy. In addition, the drives that are "grouped" can be of any size or any interface. You can have SATA, SAS, and IDE all in the same LVM. I wouldn't recommend it, but you could.

But what is it used for? Gigantic volumes, of course! Right now the largest hard drive you can buy is 3TB. What happens when you need a volume larger than that? You can use a RAID setup that will add redundancy, but you will also need a better controller and a lot more drives. But a simpler, quicker solution is to use LVM.

Here's the overview to get LVM going within Webmin:

  • Install LVM
  • Refresh Webmin Modules
  • Add a Volume Group
  • Add drives to the Volume Group
  • Add a Logical Volume within the Volume Group
  • Create the file system within the Logical Volume
  • Mount the newlycreated file system

Now for the nitty-gritty:

  • From the command line, install LVM
  • sudo apt-get install lvm2

  • Once LVM is installed, refresh the modules within Webmin
  • With Logical Volume Management selected under the Hardware menu, click on the Add new volume group link

What Went Wrong With Modern Warfare 3

I've picked up MW3 again recently and have come to the conclusion that it is nowhere near Black Ops for multiplayer. It's not, and I have my reasons. I think that Infinity Ward did some things correctly when it came to multiplayer, such as adding Kill Confirmed and introducing a Death Streak system. Unfortunately the bad far outweighs the good, and for this I think that BO2 will be the major step forward that MW3 should have been. First, the good:
  • Kill Confirmed

Drupal in the Cloud, Part 2D: Rackspace's Cloud Servers

Rackspace is another (awesome) option for a cloud service provider. I think their interface is extremely easy to navigate, and you have the added bonus of getting an external IP immediately instead of having to assign an external IP. The benefit of this is that your server, as long as it stays on, retains the IP.

So, go forth and create a Rackspace account! When you are done, come back and follow these instructions:

  • Click on the Cloud Servers in the left-hand side menu
  • Click on the Add Server button
  • Select the distro you wish to use. I recommend Ubuntu 12.04
  • Give your server an internal name and the size. I'm setting mine up as a 256MB instance. Don't sweat this step, as Rackspace allows you to easily resize the server in minutes.
  • You will be given a password. Store this in a secure location and select Close Window
  • The building process will take about two minutes, in which time you can grab a drink, refill, or just watch the progress-o-meter

Drupal in the Cloud, Part 3: Installing Virtualmin

Let me preface this section with a caveat: you do not need Virtualmin for Drupal to work. Drupal will work just fine without Virtualmin, provided it gets the three things it does need: Apache, MySQL, and PHP.

For those at home taking notes, this is typically called a LAMP setup- Linux, Apache, MySQL, PHP. LAMP. Get it? Cool, let's continue.

What Virtualmin does is provide an easy interface to manage your server, which is an absolute godsend for those who hate doing things by command line.

There are three things we need to get Virtualmin up and running:

  1. Be on a supported system (CentOS, Debian, Ubuntu LTS, etc.)
  2. Change the hostname to what its final hostname will be
  3. Run the install script

The first requirement is done, provided you have been doing things according to the tutorial.

The second requirement is fairly easy:
