Covers the role of QDevices in stabilizing a 2-node cluster, storage requirements for HA VMs, and step-by-step instructions for installing a QDevice on a Raspberry Pi. Also explains the limitations of QDevices in 3-node clusters and how to verify the setup using pvecm status. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How do I install a QDevice on a Raspberry Pi for a Proxmox cluster? Enable root SSH login on the Pi by setting a root password with `sudo passwd root`, editing `/etc/ssh/sshd_config` to set `PermitRootLogin yes`, and restarting sshd. Install the QDevice daemon on the Pi, then run `apt install corosync-qdevice` on every Proxmox node. Finally, run `pvecm` from any cluster node with the Pi's IP address to register the QDevice. Verify with `pvecm status`. _Homelab operators running Proxmox HA setups share QDevice configs and gotchas on daily.dev._ ### How do I verify a Proxmox QDevice is working after installation? Run `pvecm status` from any cluster node. The QDevice appears under `Membership Information`, and `Votequorum Information` shows total votes and the quorum threshold. The `QDevice` flag is also listed under `Flags`. Note that the QDevice does not appear anywhere in the Proxmox web GUI, so the CLI check is the only way to confirm it is active. _Proxmox cluster operators troubleshooting quorum issues find relevant discussions on daily.dev._ ## Similar posts on daily.dev - [High-availability is overkill for the average Proxmox home lab, and chasing it is how people wreck their setup](https://daily.dev/posts/high-availability-is-overkill-for-the-average-proxmox-home-lab-and-chasing-it-is-how-people-wreck-t-exmqpt0w5) · XDA Developers · 0 upvotes · 0 comments - [More random home lab things I've recently learned](https://daily.dev/posts/more-random-home-lab-things-i-ve-recently-learned-e7ucih6lp) · Hacker News · 10 upvotes · 0 comments - [How I Organize My Self-Hosted Apps and Dev Environment](https://daily.dev/posts/how-i-organize-my-self-hosted-apps-and-dev-environment-xlt9ry2an) · Noted · 21 upvotes · 2 comments - [I always tweak my Proxmox host's settings before spinning up a single VM or LXC](https://daily.dev/posts/i-always-tweak-my-proxmox-host-s-settings-before-spinning-up-a-single-vm-or-lxc-j7bpwodpd) · XDA Developers · 0 upvotes · 0 comments --- Tags: [#raspberry-pi](https://daily.dev/tags/raspberry-pi), [#proxmox](https://daily.dev/tags/proxmox) [View this post on daily.dev](https://daily.dev/posts/small-proxmox-cluster-tips-and-tricks-and-qdevices-3kkp6qxkq) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Small Proxmox Cluster Tips and Tricks, and QDevices","url":"https://daily.dev/posts/small-proxmox-cluster-tips-and-tricks-and-qdevices-3kkp6qxkq","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/small-proxmox-cluster-tips-and-tricks-and-qdevices-3kkp6qxkq"},"datePublished":"2026-08-11T08:56:31.073Z","dateModified":"2026-08-11T09:10:20.447Z","description":"A practical guide to setting up small Proxmox clusters of 2-3 nodes, focusing on quorum management and high availability.
