Working with logical Volumes (part 3)

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 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.

About the ad’s

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:

  1. 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.)
  2. They can be annoying.
  3. 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.

  1. 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.
  2. 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.

Working with logical volumes (part 2)

In this post I want to cover one of the most commonly used features of lvm, extending a logical volume. If you were following along with the last post, “Working with logical volumes part 1”, then you should already have a volume group with a couple of live volumes attached.

With lvm you can quickly and easily extend a Linux file system on the fly without interrupting any services.
