> As an aside... Because one node didn't start, and my Proxmox cluster has only two nodes, it can't reach quorum, meaning I can't really make any changes to my other node, and I can't start any containers that are stopped. I've recently added another Zigbee dongle, that supports Thread, and it happens to share same VID:PID combo as the old dongle, so due to how these were mapped into guest OS, all my light switches stopped working. I had to fix the issue fast.

Lesson in here somewhere. Something about about a toaster representing the local intelligence maxima?

The lesson is use dumb light switches and have a shotgun ready if the printer starts to act up.

Also regularly print out sheets of electronic recycling facts to remind the printer of its place.

I see you made the mistake of buying an hp inkjet in the last twenty years as well...

Lesson 1: clusters should have an odd number of nodes.

[nightpool]

I really, really think there are better lessons there. Maybe more like "Lesson 0. Don't put distributed clusters in control of your light switches"

[KetoManx64]

Yes, but then I'm going to have to manually go around my house and turn off all the lights when I leave the house and when I come back I have to turn them on manually instead of them just turning on when I open the door to a room. Also my AC/heating automatically turns off when I leave the house and turns on when I come back, my lights automatically dim/change to a warmer temperature in the evening as it gets closer to bed time, my desktop goes to sleep when I leave the house, my TV automatically turns on when I power on the living room media PC, etc. etc.

Why not?? It's fun!

Two node / even node clusters can work fine.

For even n>2 you define a tie breaker node in advance and only the partition connected to that node can make a quorum at 50%. For n=2 going from no quorum to quorum requires both nodes but losing a node doesn't lose quorum, and when you lose a node you stop, shoot the other node, and continue. For split brain the fastest draw wins the shootout.

I bet there is still space for a race condition there.

Originally I was planning on building the NAS with just the Minisforum MS-01, but truenas and USB enclosures do not play well together.

So I went for the AOOSTAR NAS mini-pc as a "proper" solution. Ended up with two machines, so why not join them into the cluster!

Probably can chuck proxmox on a RasPi somewhere, just for quorum purposes :)

[znpy]

In fairness to proxmox, that's the recommended way.

Most homelabbers ignore recommendations because if anything breaks nothing of corporate value is lost and no one's gonna lose their job.

[holysoles]

proxmox even makes it easy by letting you run something like a raspberry pi as an additional quorum member if you dont have enough hardware for a 3rd node

[vsviridov]

At least I was laughing at the Cloudflare oopsie, since all my light switches (et al) are all local. Unlike those people with a fancy smart bed that went into a W shape because it couldn't talk to AWS.

[Saris]

Yup, if you're going to have smart lights, get ones that still have a physical switch!
