So, lets talk about containers.
Lately, I’ve been spending quite a bit of my time trying to learn as much about containers as I can. Truth be told I don’t really like containers, for the most part I think they tend to add an unnecessary layer of complexity into my infrastructer and become just one more thing to firewall, patch, and maintain a separate lifecycle for. However, it seems that I am in the minority opinion regarding this technology so I’ve been making an honest attempt to learn about the various container technologies and see if I can apply any of it to my day to day activities. I am open to the possibility that, maybe, I haven’t put in enough work to gain an appreciation of Docker, or LXC, or Atomic, or CoreOS, or whatever other new fangled technology these young folk are into 🙂 To that end I’m hoping over the next few months to identify some portion of this site that can be moved into a container to find out what I’ve been missing! Who knows maybe I’ll find out I like containers.

Following this tutorial assumes that you have followed along with the other two parts in this series. However, if you already have some familiarity with Linux you should be able to follow along.
Working with logical volumes (part 1)
Working with logical volumes (part 2)
Add a disk to the volume group
One of the great things about lvm is that you can add and remove physical volumes on the fly without data loss and without interrupting services.
If you haven’t already done so, add a new hard disk to your virtual machine. I created an additional 10 GB disk but you can make the disk any size you want. It doesn’t have to match the previous disk that we created.

Why are there suddenly ad’s on this site?
So, recently I enrolled this site into Google’s AdSense network. It’s something that I really didn’t want to do, and am still a little torn about it.
I don’t like ad’s on web pages for a number of reasons:
- I think pages with ad’s feel less credible. So I’m going to try to limit the number of ad’s on each page to one or two. ( I know there are some with more than that right now… I’m still experimenting with how it works.)
- They can be annoying.
- The advertisement revenue model rewards click bait that generally has crap content.
So why did put ad’s on my pages? I have a few reasons for doing so that I hope the two or three people who read my blog regularly this can empathize with.
- The cost of keeping this site up and running is not insignificant. Hosting charges add up and I’m hoping to generate enough revenue to break even.
- It’s the easiest way to fund this account at the moment. I’ve kicked around the idea of using Patreon and I still might, but for now I’m going to stick with the advertising and see how it goes.
If you notice an ad that is offensive or if you find them too distracting let me know in the comments and I’ll try to either refine the placement of the ad’s or in the case that something is offensive I will do my best to remove it.
