SMALL Proxmox Cluster Tips | Quorum and QDevices, Oh My! (+ Installing a QDevice on a RasPi)

Video Description

So you want to turn your one or two Proxmox nodes into a small Proxmox cluster? What do you need to know about quorum, especially as it pertains to really small clusters of 2 and 3 nodes? In this video, I go over the different ways to stabilize a 2-node cluster for high availability, the storage requirements for high available VMs, using a Raspberry Pi as a QDevice, and if you even need one. I also talk about how a QDevice might not help you as much as you think in a 3 node cluster. I also cover installing a the QDevice daemon on a Raspberry Pi, and using a very small Proxmox node to maintain quorum without allowing it to be part of the high available VM pool.
