Surfaced by the new node_health DIMM reporting, unrelated to the memattr bug and NOT a fault: DIMM1 is a Micron 8ATF2G64HZ-3G2E1 (DDR4-3200), DIMM3 a Micron 16ATF2G64HZ-2G6E1 (DDR4-2667). Both 16 GB so capacity is right, but different rank organisation and rated speed mean the pair runs at the slower 2667. Recorded in §0 where the symmetry decision gets made, because §2 requires the three nodes to end up with identical layouts and the previous '2x16 GB Micron' note hid the mismatch. Serves: R-ENV-03. Task: T-7.1.
infra/ — node provisioning and the toolchain
OpenTofu (Proxmox VE) + cloud-init + Ansible bring up the 3-node k3s/Cilium dev cluster.
Spec: ../home-network-k3s/docs/02-environments-and-provisioning.md.
| Path | What |
|---|---|
tofu/ |
The "Create" stage: 3 cloud-init'd VMs on the Proxmox box (bpg/proxmox provider) |
cloud-init/ |
First-boot baseline shipped as a Proxmox user-data snippet |
ansible/ |
The "Baseline"/"Configure" stages: k3s HA, Cilium, kube-vip, the VPN egress gateway |
devcontainer/ |
The pinned toolchain (tofu, ansible, sops, age, flux, kubectl, helm and the whole CI gate toolchain) |
cluster.sh |
RETIRED — drove the old libvirt VMs; does not work against Proxmox |
PHASE1-STATUS.md |
Current state of the cluster and how to reconnect to it |
PHASE1-SCOPE.md |
Historical Phase-1 scoping doc (libvirt era — superseded) |
Where the cluster actually lives
The dev cluster is not on this workstation. It runs on a Proxmox VE host; the nodes sit on the Proxmox LAN and are reached across a pfSense NAT:
| Nodes | k3s-dev-1/2/3 at 192.168.1.50/.51/.52 — 6 vCPU, 24 GiB, Debian 13, k3s v1.36.4 |
| kube-API | kube-vip VIP 192.168.1.49:6443, reached from the workstation via NAT 192.168.2.50:6443 |
| Node SSH | pfSense NAT 192.168.2.102:2250/2251/2252 → node :22 (Ansible only) |
| Ingress VIP | 192.168.1.53 (Cilium L2, shared Gateway); .53–.60 reserved for LB VIPs |
The earlier libvirt/KVM cluster on 10.73.0.0/24 is retired. Any doc or command referencing
virsh, qemu:///system, or 10.73.0.x for the cluster is historical.
