  • Thank you for the feedback, could you be more specific?

    Is it crossposting? Or Kubernetes-specific content in /c/programming?

    Or giving tips on how to practice for specific certification exams?

    Or do you dislike the prose format? Too much context? Do you prefer bullet points?

    Or is it that I put an image while the link should be the focus? I see now that in my client I have to click through to the original post first to see and visit the URL




  • I don’t believe you, but I’d like to be proven wrong.

    I expect you have a UPS that feeds your hosts and networking equipment and something like ZFS for disk redundancy. This protects against the most common failures and is usually enough, but there are still single points of failure in such a setup, that are not as common, not as hard to deal with through manual intervention, and quite difficult to protect with redundancy.

    I would be surprised if you are protected against the following single points of failure without manual intervention:

    • NAS machine (not just disk) failure. You would need to have a multi-node distributed storage, like Ceph, to protect against this.
    • Networking equipment failure. I think you can do some magic with BGP to do this, but I’m not a network engineer and I’ve never set up a redundant network.
