Brilliant
highly underrated channel, bro you must rock this domain on YT

Great video Morris, subscribed! Would love to hear more about your home cluster setup and how it's built 🙂

i wonder why you're not producing videos any more, it's like i have all your videos saved, they're really valuable

[TheOnlyEpsilonAlpha]

Thanks for the video. I find it ridiculous, that Kubernetes by itself is high available, failover and everything but when a node goes down the storage is lost!?!? I mean for real? Ceph should be the(!) default storage for Kubernetes

... little background.
i have a 3 node proxmox cluster. each have a 1TB NVMe drive, partitioned into 200GB to Proxmox and 800 given to CEPH as cephpool. My 3 Master nodes and 3 worker nodes (ubuntu 24.10 based) are created on this cephpool allowing me to migrate my VM's onto any of my physical nodes. at the moment they basically just have space allocated for the os and for the k8s software.
My understanding is I will be adding say an addition 100GB to each of the workers, which will then be given to ceph/rook to be installed inside my K8S cluster,
be great if you had some diagrams of what you were doing and how things are layered.

Thank you. Can you please elaborate why and on what basis the osd's are created on all of your 5 nodes?

[georgelza]

do assign the space to the worker nodes i assume... ie not the master nodes.

Thank you so much for your tutorials. They have taught me a lot. However, I am having issues with installing Rook Ceph. I don't know if it is because i am using kube-vip in my cluster. Please, any pointer will be appreciated. Best regards

[sourabhdey]

how can we intergrate the external ceph cluster with kubernetes cluster ?

[nuchallenger]

How should I adopt this to work with my aks cluster? Will I need to change any of the operator settings?

Hi mate,

Do you know if this solves the sqlite concurrency issues. That is because many of the self-hosting applications (navidrome, jellyfin) rely on sqlite and it is not possible to run more than one replica without locking the database. I tried Longhorn and had this problem.
