  • reducing power consumption of proxmox nodes

    I noticed the other day that my proxmox nodes are running at max turbo frequency all the time. Even when there is virtually zero activity, the 8700 and 7700k are sitting at 4.2ghz+ on all cores. The little x270 stays locked at 3.4ghz on its two cores. Since these servers idle a huge amount, they…

  • electrical engineering: a cooling solution

    I have 6 SFP+ ports on my new switch, but so far I only have one 10-gig ethernet device and a couple of 2.5-gig ethernet devices. How do I plug those mugs in??? Enter the transceiver — Mikrotik S+RJ10 This little booger allows you to plug in any ethernet device up to 10 gigabits into…

  • summer server upgrade wrap-up

    It’s finally upgrade time! >(click here to skip to the new stuff)< I originally built this homelab cluster in December of 2022 for a few reasons: for fun, for learning, and to help me pivot my career away from manufacturing and into IT. I saved up a bunch of money, quit my factory job, and…

  • proxmox: get rid of gray question marks

    Sometimes you might find that one of your nodes and all its containers, VMs, and storages have gray question marks beside them. This happens because the cluster has lost quorum. When this happens, sometimes you can even still see the real-time stats in the summary page the node and machines still ticking along. Here’s the…

  • file server backup times: lxc and vm

    THE OLD: I have been using a fileserver in a Turnkey debian 11 container for several months. I allocated 8gb of the ssd for bootdrive and 2TB of my zfs pool for storage. The zfs pool is comprised of 3 old Western Digital green drives, WDEARS20, in a raidz1 configuration. It is connected with a…

  • random linux tips and tricks: february

    Here are some random things I learned this month! find files way faster than “find” with mlocate This one is cool! “Find” can be a pain in the butt sometimes, and it’s really slow if you have a large drive with lots of files on it. Using mlocate, you can find files nearly instantly by…

  • state of the cluster: 1/23

    The homelab has come a long way in the past couple of months. It’s still a heap of e-waste, but now it’s a BIG heap of e-waste! It’s been so fun to learn all of this stuff. It’s been so fun, in fact, that I want it to be my job. How it started: It…

  • speed up your nextcloud server

    By default, Nextcloud has object caching disabled. It also triggers the background tasks to be run on every page load by default, using AJAX instead of using a cron job on a timer. This was causing a significant delay for my friends accessing my server. Following a couple other guides on the internet, I found…

  • tls_process_server_certificate: certificate verify failed (596)

    Sometimes I get this error message in Proxmox after making a network change, messing with an ssh key, or some other random mistake. Once this happens, the nodes in my cluster become inaccessible through the admin interface. Here’s how I get the cluster running again: Copy and paste the command that ssh spits out to…

  • Easyengine – simple wordpress + ssl deployments

    Baby’s first VPS! Now that the homelab cluster is running multiple external services, I’m starting to hit some speed bumps. Using my single domain name with tons of port numbers was working okay to keep services separated for personal use. But now with friends and family connecting and using some of these services, it’s time…
