ZFS tiering: special vdevs and hybrid pools

Techno Tim joins Adam to dive deep into the state of homelab’ing in 2026. Hardware is scarce and expensive due to the AI gold rush, but software has never been better. From unleashing Claude on your UDM Pro to building custom Proxmox CLIs, they explores how AI is transforming what’s possible in the homelab. Tim declares 2026 the “Year of Self-Hosted Software” while Adam reveals his homelab’s secret weapons: DNSHole (a Pi-hole replacement written in Rust) and PXM (a Proxmox automation CLI).
