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
I’ve been using Longhorn in an on-prem cluster for the last two years. I use it to manage state for running applications. Longhorn let’s me avoid using a NAS or other mounted volume and, so far, has done a good job of maintaining data integrity when I’ve lost a node or two.
Been using longhorn for my homelab for a while now, I love it. Can’t comment on how it is for production, but I wouldn’t hesitate to give it a try if I were to ever setup an on-prem cluster again.
Which Pi hardware and OS are you running? I’m fixing to stand up two Pi 4’s and about four Pi 3Bs. I was planning to run Ubuntu Server 22.04 arm64.
