It’s ok that you had the original idea to steal my idea, I stole the idea too 😂

[icequark]

"Cause I can, and I am a nerd." Words to live by.

The way to get your workloads to prefer a node is to create HA groups for each node. Set the node priority for each group to be the same for all the non preferred nodes, and increase that value by one or two for the preferred node.

Workloads will migrate to the node that is up with the highest priority first, and then prefer nodes of equal priority with the most amount of free memory and lowest CPU usage

[DerUser]

Built a cluster with 3x Minisforum EliteMini HM90 with 32GB RAM (max. is 64GB) + 512GB NVMe + 1TB SSD each - plenty of cluster power with (3x9=) 27 Watts idle.
The mini PCs also have two NICs so I'm running a separate Cluster Network for running the synchronization of the nodes as a best practice tip from Proxmox says: "Storage communication should never be on the same network as corosync!"
Actually didn't want to run out of CPU power even when operating the one or another Windows OS on the cluster.
Anyway: Proxmox rocks! Hope to see more content on your channel - which is one of my favorites. 👍🏻

This is such a cool project. Hadn't taken this board seriously until you posted this but now I keep thinking about it as I'm trying to adjust my new southern, basement-less lifestyle where I'm baking my wife in her office with my homelab servers.

[jeytis]

Very informative and clear. I have now a better understanding about how a Cluster and Ceph work in Proxmox. Thanks

[GeoffSeeley]

As others have commented, Ceph needs more memory but it should also have it's own isolated (preferably) network, the faster the better. It will constantly be copying changed blocks on one node to the other two nodes to stay in sync. You should use that second NIC on each node for this.

Thank you for making this video! Proxmox cluster was the very next thing on my lab to do list!

That's exactly my reasoning for most of my Home Lab projects.

[lamar]

Thank you, another rabbit hole for me to go in.

[patrickpaganini]

"Or if you want an actual good video ..." lol, that took me by surprise - good to have a sense of humour!

[NightHawkATL]

Great video! I ultimately want to get to this point as well and possibly include plex in a supermicro 1u cluster with a p400 in each.

[LeoNux-umtg]

I'm going to build my proxmox server with my old 3rd gen quad core laptop. Thanks for inspiring me

[corpdecker]

Ayee, that map screenshot shows my house. What a small world.
I need to set something like this up, but w/ more power than the ZimaBoards. I know all the options, but it's hard balancing performance vs cost vs efficiency. Thanks for the vid!

[thespencerowen]

Such a great video. I’m doing the exact same thing with intel nuc. I use ceph at work and I despise it, but seeing how simple it is inside of proxmox has convinced me to try it at home.

Shoutout to the artisanal mountain monks making beautiful server racks

[saltlakrids]

I absolutely love your easy way of explaining. Subscribed ;)

[festro]

I'm surprised back-plane pcie interconnects aren't a thing with SBCs like this, would make for far better clusters.

[BrianThomas]

I've done the same exact thing on 4 different small form factor hardware. I'm running Open Media Vault which file sharing and docker, portainer support running all kinds of cool stuff. The must have was a UNIFI controller in docker. Having that in a HA cluster on battery backup is AMAZING!. It's very cool. I'll have to give the CEPH a try though. This looks like it save me some power. I'm using an NSF cluster for HA storage on 3 other mini PCs.

[prashanthb]

Only 10 watts and so much functionality is definitely a winner.
