Part 4 found four gaps the hard way, live, under pressure. This is the same migration run against tanaka the very next day with all four fixed proactively — plus a real hardware detour before any of the software even mattered, and one genuinely new finding Part 4 never hit.

Part 3 laid out the plan for migrating to smaller SSDs. Here's what happened running it against a real node with both mirror drives failing at once — a UEFI dead end (the third one), four gaps the plan never anticipated, a mistake I made and had to recover from live, and a real hardware failure that surfaced while fixing the last gap.

Migrating a Proxmox ZFS boot mirror from large spinning rust HDDs to smaller SSDs — why a fresh install with a UEFI upgrade is the practical path.

When both drives in your ZFS boot mirror fail simultaneously, you can't resilver your way out. Here's the full procedure for a Proxmox fresh install that preserves your Ceph OSDs and rejoins the cluster — based on a real harlan node recovery.

ZFS boot mirrors saved my homelab cluster more than once. Here's the complete procedure for replacing a failed drive in a Proxmox ZFS boot mirror — including the mistakes I made so you don't have to.

A routine ZFS scrub alert on harlan turned into a multi-hour debugging session when a hostid mismatch fix collided with a pre-existing Ceph OSD failure from a dead USB drive. Here's how overlapping storage problems can mask each other and how to untangle them.

Automated SMART monitoring and cost planning for ZFS boot mirrors across a six-node Proxmox homelab cluster with mixed SSD/HDD hardware. Track drive health, plan replacements, and manage homelab storage costs effectively.
