    When I bought my Hyundai they pushed fucking hard to sign up for their Blue link product. Free for life! Look, map updates! You can personalize your driver profile pic! Want to remote start your car over the Internet?

    Luckily, my VIN wasn’t working for registration (I guess it hadn’t quite gone through fast enough that the car was purchased). I’ve gone two months without BlueLink and I’m hoping that’s saving me from some of the info gathering (or at least it’s not directly linked to me.












  • Not really, but I can give you my reasons for doing so. Know that you’ll need some shared storage (NFS, CIFS, etc) to take full advantage of the cluster.

    1. Zero downtime for patching. Taking systems offline to update Proxmox sucks, especially if the upgrade fails for some reason. A cluster means I can evacuate one host, upgrade it, and move on to the next with no downtime for the hosted VMs.
    2. Critical service resiliency. I have a couple of critical systems in my home lab that, if they unexpectedly go down, will make for a very bad day. For instance, my entire home network (and lab) is configured to use a PowerDNS cluster for DNS. I can put the master PowerDNS server on one host and the slave on a second host - if I have a hardware failure, I won’t lose DNS. I have a similar setup for my Kubernetes cluster’s worker nodes.
    3. Experimentation. A cluster gives me a larger shared pool of CPU/Memory than my single host could offer. This means I can spin up new VMs, LXC containers, etc and just play with new software and services. Heck that’s how I got started with my Kubernetes cluster - I had some spare capacity so I found a blog post that talked about Kubes on LXC containers and I spun it up.

    I hope that helps give some reasons for doing a cluster, and apologies for not replying immediately. I’m happy to share more about my homelab/answer other questions about my setup.
