Covers node 1 hardware/network layout, LVM-thin -> ZFS migration path,
Ceph as the future HA storage upgrade, and baseline SSH/firewall
hardening.

Proxmox Configuration

Config, planning docs, and scripts for rebuilding my Proxmox VE homelab on new hardware, with the end goal of a 3-node HA cluster.

Goals

Fresh install on new hardware (old box has a KVM/virtualization bug that forced disabling hardware-accelerated virtualization — not expected to recur on new hardware; verify VT-x/AMD-V + IOMMU in BIOS before assuming otherwise).
Move off LVM-thin to ZFS for local storage.
Build node 1 so its disk and network layout doesn't need rework when nodes 2 and 3 are added later.
End state: 3-node cluster, quorum via corosync, HA-managed VMs backed by ZFS replication and/or Ceph.

docs/ — planning docs: hardware layout, storage migration, networking, security hardening. Read docs/00-overview.md first.
scripts/ — scripts to apply configuration on a node (SSH hardening, repo switch, etc.). Idempotent, safe to re-run.
config/ — reference config files/snippets to drop onto a node (firewall rules, sshd config, etc.).

Planning stage — node 1 not yet built.
