044 - Hyper-V Failover Clustering in 2026

Failover clustering is the part of Hyper-V that trips up the most people, especially anyone arriving from the VMware side. In this episode Andy Syrewicze and Eric Siron pick up directly where episode 043 left off: you have standalone Hyper-V running, now what does it actually take to make it highly available in 2026?The guys start with the "why bother" question: Azure Local versus a traditional Hyper-V failover cluster comes down mostly to billing and governance overhead, not capability. From there the conversation moves into prerequisites: shared storage options (Storage Spaces Direct, iSCSI, SMB shares, Fiber Channel), Active Directory integration, and the heartbeat NIC myth Eric has been fighting against since he started seeing outdated Microsoft docs still getting passed around. The bulk of the episode is quorum: what split-brain means, why a two-node cluster needs a third vote, and the practical tradeoffs between a file share witness, a disk witness, and a cloud witness in Azure. Dynamic quorum gets its own explanation, including how graceful node shutdowns allow a cluster to shrink without taking everything offline. They close on the creation experience (PowerShell over Windows Admin Center, period), the gotcha that catches every VMware migrant (creating the cluster and adding VMs as clustered roles are two separate steps), live migration and shared nothing live migration.In the news and nerd hour segments this week: the FCC ban on foreign-made consumer routers (with Netgear already approved as an exception before anyone finished reading the press release), 3D printing of circuitry using microwave-based manipulation now down to the width of a human hair, Tim Cook stepping down from Apple, Andy using Claude Code to build a master index of every topic covered across all 43 episodes and every newsletter edition, and Eric deep in research on a home routing setup built around a mini PC with a separate router component so the internet does not require an IT degree to reset when he is traveling.---## Episode ResourcesSysAdmin Weekly Website: https://www.sysadminweekly.comSysAdmin Weekly Companion Newsletter: https://newsletter.sysadminweekly.comCommunity Discussion Board: https://github.com/ProjectRunspace/sysadmin-weeklyShare Your Family/Friends IT Support Stories (community post): https://github.com/ProjectRunspace/sysadmin-weekly/discussions/15AndyOnTech: https://www.andyontech.comProject Runspace: https://www.projectrunspace.org**Previous episodes referenced in this episode:**- Episode 043: Getting Started with Hyper-V in 2026: https://open.spotify.com/episode/4J77iiMVDWvvf8fshSurAL?si=D1hPaG7eSKiX6uU7UPBL3g- Episode 042: Should SysAdmins Job Hop or Stay Put?: https://open.spotify.com/episode/0o7EMW8JTGDm8rJv7Xu6Pg?si=uv1KIDZwS-y4l0g6yIV8jA- Episode 13: Should Hyper-V Be Domain Joined?: https://open.spotify.com/episode/0KWjIe5xgqZV9XYHuV2UF3?si=oK6XKjJiQ_mvpEEDqY_vyg- Episode 017: Hyper-V Management Story episode: https://open.spotify.com/episode/0rHwIc4U297R7I6KFayhlm?si=oTB7nX3bTgG7xekebnIU5g**Articles referenced in this episode:**- FCC ban on foreign-made consumer routers: https://www.wired.com/story/us-government-foreign-made-router-ban-explained/- What's New with Hyper-V in Windows Server 2025 (Microsoft Docs): https://learn.microsoft.com/en-us/windows-server/get-started/whats-new-windows-server-2025#hyper-v-ai-and-performance---## Chapters03:30 - Tech News Highlights14:38 - Nerd Hour: Personal Projects and Innovations21:02 - Listener Feedback and Career Insights25:54 - Hyper-V Failover Clustering in 202632:56 - Automated Setup and Shared Storage Solutions35:03 - Active Directory Integration and Clustering Best Practices36:55 - Understanding Quorum in Failover Clustering46:15 - Establishing a Failover Cluster: Tools and Processes57:18 - Live Migration and Storage Migration in Hyper-V01:01:14 - Day Two Operations and Cluster Management
