Tried it out in the past couple of days to manage k8s volumes and backups on s3 and it works surprisingly well out of the box. Context: k3s running on multiple raspberry pi

    Please do not use my bad experience stop you! Longhorn is a nice tool and as you can read online and in other posts it works very well. I may have unlucky, have a bad configuration or had my PIs under too much pressure. Who knows! My advice is try something new: k3s, longhorn, etc. That is what I use the PIs for. I would not use Longhorn at work :D

    I’m really not sure what I even want the distributed FS for. I guess I wanted to have redundancy on the pod long term storage, but I have other ways to achieve that.

    I am not using replicas :) I use longhorn for the clean/integrated backup mechanism instead of using something external. Maybe one day when I have the same-ish disk speed on all 3 PIs I will enable replicas but for now I am good like this.

    For backups of important stuff maybe use something else or ALSO something else. I was personally thinking to use another backup too for longhorn devices like https://github.com/backube/volsync or velero to have a secondary source in case something happen. Also longhorn is always getting better. This is just out of the press https://github.com/longhorn/longhorn/releases/tag/v1.5.0

    My advice? Try it out! If not, it will still be a source of learning and fun (but I am strange, I like to debug stuff).

      I’m having enough trouble trying to get k3s running. I keep getting apiserver unavailable, connection refused, etc. kubectl works about 1/10th of the times I call it. I loaded the OS on external HDD to see if that was the problem but no dice.

        Sorry to hear. If you had NO connection with kubectl, I would have adviced you to check the ports; but if sometimes it replies and most of the time not, it must be something else. Good luck with the debug and if you have any specific problem you could also try to create a post on any of the self-hosted communities here on lemmy. From my experience people is more friendly and more technical than what we used to have on reddit.
