Finally have btrfs setup in RAID1

A little under 3 years ago, I started exploring btrfs for its ability to help me limit data loss. Since then I’ve implemented a snapshot script to take advantage of the Copy-on-Write features of btrfs. But I hadn’t yet had the funds and the PC case space to do RAID1. I finally was able to […]

LXC Project Part 3: Starting and logging into my first container

Continuing my LXC project, let’s list the installed containers: lxc-ls That just shows the name of the container – lemmy. For completion’s sake, I’m going to start it as a daemon in the background rather than being sent straight into the console: lxc-start -n lemmy -d As per usual Linux SOP, it produced no output. […]

I’m starting with Centos 7 so the first thing I had to do was enable the epel repos: yum install epel-release Then, according to the guide I was following, I had to also install these package: yum install debootstrap perl libvirt […]

First I installed bridge-utils: yum install bridge-utils -y After that, I had to create the network script: […]

How did I not know about LXC Containers?

Back when I first was working on replacing my Pogoplug (the original BabyLuigi), I was looking at potentially using it to learn about Docker in addition to creating virtual machines that were actually useful instead of just playing around with VMs for looking at Linux distros. The benefit of Docker was to have the isolation […]

Using Flatpak to install LibreOffice on Fedora 24

After someone told me that a PDF I’d created in Calligra Office was illegible and having issues with spreadsheets loading slowly, I decided to install LibreOffice. However, rather than go with the version in the repos, I decided to go with Flatpak – which allows for a more advanced version via the usage of runtimes. […]
