  • Daisy (laptop) upgrade to Fedora 31

    When I tried to upgrade the laptop a couple days ahead of the Tuesday release date, assuming that the sources were as good as gold at that point, the upgrade process complained about the Kdevelop Python plugin and didn’t want to proceed. I figured if this persisted past Tuesday I would just use it as…

  • Fedora 31 is coming; Getting on Fedora 30

    Back when Fedora 30 came out, I updated my laptop, but I left my main computer and the HTPC on Fedora 29. The former because I was busy with something at the time and didn’t want the disruption of an upgrade; the latter because the family depends on it for entertainment. However, with Fedora 31…

  • Red Hat Summit 2019

    Red Hat Summit 2019

    Red Hat Summit 2019 was my first Red Hat Summit. I heard quite a few people saying it was the largest one they’d been to yet and that it used to be a pretty small convention. That was not the case this year; it used up the entire Boston Convention Center. I’ve said before, concerning…

  • Upgraded Laptop to Fedora 30

    Now that I’m back from Red Hat Summit, I am ready to start upgrading my Fedora computers. Well, probably not the server or the living room HTPC – I’ll take advantage of the fact that Fedora supports the n-1 release to reduce headaches and downtime. As I’ve done for a few releases now, I used…

  • The self-hosting journey continues

    Although I’ve had a website since the mid-90s, it was 2005 or thereabouts that I first started hosting my own sites rather than relying on other sites. The first bit of hosting involved blogging and I tried a few different software packages before settling on WordPress. And other than playing around with phpBB for my…

  • CentOS 7 works on Acer Aspire One D255E

    Often people try and dissuade you from installing CentOS onto a laptop because they say the chipsets on the laptops are so varied it’s likely you will end up unable to use your laptop because the drivers aren’t there. Well, I don’t know if it’s because this netbook is so old (I mean, netbooks as…

  • Attempting to use Clonezilla to clone my server

    My main server, Tanukimario, has a 120GB hard drive in it and it’s started to become annoying to butt up against that limit. I have an 512GB SSD that I only used for a couple years that I wanted to use as a replacement. In order to reduce the annoyances that come from setting things…

  • HDRMerge and CC Extractor RPMs

    A while back I created a copr repo for HDR Merge. I hadn’t kept up with it because there weren’t regular HDRMerge releases going on, but I noticed the git repo has been very active, so I decided to create a new RPM for Fedora 29. And recently I learned that for the newest version…

  • Another piece falls into place for Docker

    Another piece falls into place for Docker

    Yesterday I was at a conference dedicated to DevOps and so Red Hat and Google were there to talk about containers, especially Docker and Kubernetes. While summarizing it to some of my employees today, I was asked about what I see as the benefits of Docker containers relative to Virtual Machines. I mentioned that one…

  • Stratis or BTRFS?

    It’s been a while since btrfs was first introduced to me via a Fedora version that had it as the default filesystem. At the time, it was especially brittle when it came to power outages. I ended up losing a system to one such use case. But a few years ago, I started using btrfs…

  • Speed of btrfs scrub

    Here’s the output of the status command: [root@supermario ~]# btrfs scrub status /media/Photos/ scrub status for 27cc1330-c4e3-404f-98f6-f23becec76b5 scrub started at Tue Mar 21 17:18:13 2017, running for 01:05:38 total bytes scrubbed: 1.00TiB with 0 errors So on Fedora 25 with an AMD-8323 (8 core, no hyperthreading) and 24GB of RAM with this hard drive and…

  • 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.…

    LXC Project Part 2: Setting up LXC

    I’m continuing on from yesterday’s post to get the VM ready to host LXC. 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…
