This weekend I was away from my homelab for two days. All I left behind was one Windows machine that could reach the lab's management network, which gave me the Proxmox web GUI and a console. No physical access, no keyboard on any server.
Here is an uncomfortable question for anyone running a homelab: if one of your servers died right now, how long would it take you to find out?
The power went out. When it came back, the Ceph quorum was broken, a monitor was crashing on every start, and SSH had reverted to port 22. Here's how I recovered the entire homelab 100% remotely — without touching a single cable.
Not a Raspberry Pi with Pi-hole. Not a basic NAS. A proper enterprise-grade datacenter at home — dual firewalls, 4-node Proxmox cluster, 12 VLANs, and a full service stack.
