Longhorn: Cloud native distributed block storage for Kubernetes
Longhorn: Cloud native distributed block storage for Kubernetes
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
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 model Pi? I tried it on NUCs with 4GB RAM and everything fell apart because they did not have enough RAM.
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.
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.
Two Pi4 Model B 8gb and one Pi4 Model B 4gb. OS I am using the latest ubuntu 64. A word of warning, I am having some issues with longhorn breaking the fs of my pihole pod making them "read only". I work on this stuff as a job and I still don't find a good explanation about wth went wrong. I have to be honest longhorn github issues are not very helpful nor there are good logs about it. I am starting to think there are too many microservices working behind the scene and too many gRPCs. tl;dr: it is hell to debug - I still don't find a good alternative however
