Ceph-based distributed storage requires fast networking (2.5G+), expensive hardware, and is painful to troubleshoot or dismantle. Losing quorum can leave you with a read-only UI and inaccessible VMs. For most home labbers, a simpler approach works better: split workloads across standalone Proxmox nodes — one for mission-critical services, one for experiments — and pair it with a 3-2-1 backup strategy using Proxmox Backup Server. HA clusters are genuinely useful in production or hardcore setups, but newcomers should build experience before diving in. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why would a Proxmox HA cluster end up with a read-only web UI and inaccessible VMs? This happens when the cluster loses quorum, meaning not enough nodes can communicate to agree on cluster state. Without quorum, Proxmox locks the web UI into read-only mode and virtual guests become inaccessible, which is a common failure mode in improperly sized or maintained ZFS replication or Ceph clusters in home lab setups. _daily.dev surfaces practical lessons like this for anyone troubleshooting Proxmox cluster quorum issues._ ### What network speed do I need for a Ceph cluster in Proxmox? At least 2.5G networking is recommended for a Ceph cluster to avoid slowdowns during sync and migration operations. A typical 3-node Ceph cluster can survive a broken node, but secondary workstations must be powerful enough to handle the workload, or performance suffers significantly. _Home labbers sizing Ceph hardware can track setup trade-offs like these on daily.dev._ ### Should I set up a high-availability cluster for my Proxmox home lab? For most home labs, standalone Proxmox VE nodes combined with a 3-2-1 Proxmox Backup Server pipeline are a better fit than high-availability clustering. HA clusters using ZFS replication or Ceph offer automatic failover but bring quorum risks, higher hardware and networking costs, and painful troubleshooting, making them more suitable for hardcore tinkering or production environments. _daily.dev helps developers weigh trade-offs like HA clustering versus simpler backup strategies._ ## Similar posts on daily.dev - [High availability doesn't require matching servers — my three different mini PCs proved it works anyway](https://daily.dev/posts/high-availability-doesn-t-require-matching-servers-my-three-different-mini-pcs-proved-it-works-any-1li0vlh4s) · XDA Developers · 0 upvotes · 0 comments - [Proxmox is total overkill for running a single home server, and that's exactly why you should use it](https://daily.dev/posts/proxmox-is-total-overkill-for-running-a-single-home-server-and-that-s-exactly-why-you-should-use-it-smdutocjt) · XDA Developers · 0 upvotes · 0 comments - [Proxmox Backup Server is the wrong default for small home labs](https://daily.dev/posts/proxmox-backup-server-is-the-wrong-default-for-small-home-labs-9rwdkbald) · XDA Developers · 0 upvotes · 1 comments --- Tags: [#linux](https://daily.dev/tags/linux), [#homelab](https://daily.dev/tags/homelab), [#proxmox](https://daily.dev/tags/proxmox) [View this post on daily.dev](https://daily.dev/posts/high-availability-is-overkill-for-the-average-proxmox-home-lab-and-chasing-it-is-how-people-wreck-t-exmqpt0w5) ```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":"High-availability is overkill for the average Proxmox home lab, and chasing it is how people wreck their setup","url":"https://daily.dev/posts/high-availability-is-overkill-for-the-average-proxmox-home-lab-and-chasing-it-is-how-people-wreck-t-exmqpt0w5","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/high-availability-is-overkill-for-the-average-proxmox-home-lab-and-chasing-it-is-how-people-wreck-t-exmqpt0w5"},"datePublished":"2026-07-27T13:00:53.413Z","dateModified":"2026-09-13T18:29:00.533Z","description":"Running a high-availability Proxmox cluster at home sounds appealing but comes with serious hidden costs and complexity.
