k3s-prod-2 (192.168.2.11) came online 2026-09-01. Enabled in the inventory, baseline package
floor installed, first health run completed. Vaulted become works on it unchanged.
*** OPEN FAULT: the node can only address ~2.6 GiB of a healthy, correctly-installed 16 GB
DIMM. *** Recorded in PROD-PROVISIONING §0b.
dmidecode 16 GB Samsung M471A2K43DB1-CTD in DIMM1 @ 2667 MT/s (DIMM3 empty)
BIOS e820 reports ~16 GiB usable, incl. 0x100000000-0x42f7fffff
kernel Memory: 2568544K/16546088K available (13958980K RESERVED)
last_pfn revised DOWN 0x42f800 (~16.7 GiB) -> 0xc3c10 (~3.06 GiB) in early boot
zones Normal present 3340288 pages (~12.7 GiB) but MANAGED 0
MemTotal 2,753,284 kB = 2.6 GiB
The DIMM is NOT the problem: it is present, correctly identified, and at rated speed. The
kernel sees all 16 GB and then reserves 13.3 GiB. Everything below ~3 GiB usable, everything
above 4 GiB present-but-unmanaged — the signature of memory remapping above 4 GB not being
applied, not of failing memory. Node 1 is the control: identical chassis, identical BIOS R21
Ver. 02.26.00, identical CPU, and it addresses its full 31 GiB. Per-machine state, not a
firmware-version defect.
WARNING RECORDED: do NOT assume the incoming 32 GB fixes this. If the fault is the slot, the
board or a BIOS setting rather than the DIMM, 32 GB presents identically and the money is
wasted. Verify MemTotal after any RAM change.
ALSO FOUND — the prod nodes are NOT hardware-symmetric:
node 1 Micron C400 512GB SATA SSD (~2011) — 69% life, 15 grown bad blocks, 187 erase
failures, 32 unexpected power losses
node 2 Samsung PM9A1 512GB NVMe — 96% life, 2142 power-on hours, 34 unexpected
power losses, overall-health PASSED
Same chassis, same BIOS, same CPU, same partition layout — very different storage. §2 requires
an identical disk layout across all three nodes because Longhorn replica placement assumes
symmetry, so this asymmetry is now a live input to the disk decision rather than a footnote.
Node 2's NVMe is the drive node 1 should have had.
Node 2 otherwise: 0 FAIL / 3 WARN / 12 PASS / 2 SKIP. Same three WARNs as node 1 (swap still
active pending full baseline, single IPv4 resolver, and the NVMe's 34 unexpected power losses),
plus the same unknowable-ECC SKIP.
Serves: R-ENV-01, R-ENV-03, R-OBS-04. Task: T-7.1.

# Static inventory — k3s node IPs ALIGNED with infra/tofu defaults (Proxmox migration IPs),
|
|
# but the SSH target is the pfSense NAT (see NAT HAND-OFF below) — this file is
|
|
# HAND-MAINTAINED and must NOT be regenerated from `tofu output -raw ansible_inventory`.
|
|
#
|
|
# k3s_primary = the --cluster-init server (embedded-etcd founder + Cilium k8sServiceHost).
|
|
# k3s_secondary = the two servers that join it. All three are servers (HA embedded etcd).
|
|
#
|
|
# NAT HAND-OFF (LIVE): the nodes live on the Proxmox LAN at 192.168.1.50/.51/.52, and
|
|
# Ansible reaches them over the pfSense NAT at 192.168.2.102, port-forwarded as
|
|
# 2250 -> 192.168.1.50:22, 2251 -> 192.168.1.51:22, 2252 -> 192.168.1.52:22.
|
|
# Therefore `ansible_host`/`ansible_port` below are the NAT SSH target (192.168.2.102:225x),
|
|
# and each node's REAL 192.168.1.x lives in the `k3s_node_ip` var — consumed for the k3s
|
|
# --node-ip, the API/tls-san endpoint (k3s_api_host), and general in-cluster parity.
|
|
# This file is HAND-MAINTAINED for the NAT: do NOT blindly regenerate it from
|
|
# tofu output -raw ansible_inventory
|
|
# because tofu has no knowledge of the pfSense NAT and would overwrite the mapping below.

# PROD (k3s-prod-*) — Phase 7 PREP ONLY. See infra/PROD-PROVISIONING.md (T-7.1,
|
|
# especially §5/§6) and DECISIONS-LOG.md "PHASE 7 OPENED" (2026-08-31). Node 1
|
|
# (`k3s-prod-1`, HP EliteDesk 800 G5 Mini) is on the bench and SSH-reachable; nodes 2
|
|
# and 3 have not arrived. This section is inventory/group_vars scaffolding only —
|
|
# nothing has been run against node 1, and the operator has decided the CLUSTER stays
|
|
# uninitialized (no k3s install, no --cluster-init) until all three nodes are present
|
|
# (decision #2 in the DECISIONS-LOG entry above) — no single-server-etcd window, no
|
|
# later member-add dance.
|
|
#
|
|
# KEY DIFFERENCE FROM DEV: prod sits DIRECTLY on the 192.168.2.x LAN — no pfSense NAT
|
|
# hop in front of it. Dev's `ansible_host` above is a NAT target (192.168.2.102:225x)
|
|
# that port-forwards to the node's real 192.168.1.x address, which is why dev also
|
|
# carries a separate `k3s_node_ip` per host. Prod needs no such split: `ansible_host`
|
|
# below IS already the node's real, routable address, so `k3s_node_ip` is set to the
|
|
# SAME value (kept explicit, not omitted, only so the k3s_server role's hostvar lookup
|
|
# — see the GAP note below — has something correct to find once that gap is closed).
|
|
# `ansible_port` is the node's own real sshd (22). See group_vars/k3s_prod/vars.yml for
|
|
# the k3s_api_host override that reflects this directly-reachable topology.
|
|
#
|
|
# GROUP-NAME GAP: CLOSED 2026-08-31. The roles and playbooks used to hardcode the
|
|
# LITERAL dev groups (`hosts: k3s_servers` / `k3s_primary` / `k3s_secondary`, and
|
|
# `groups['k3s_primary']` inside roles/k3s_server + roles/cilium), so nothing could
|
|
# select the k3s_prod_* groups below. Both halves are now variables, deliberately kept
|
|
# separate because Ansible resolves them at different times:
|
|
# * WHICH HOSTS A PLAY RUNS ON — `k3s_hosts` (whole-cluster plays), `k3s_primary_hosts`
|
|
# / `k3s_secondary_hosts` (k3s.yml's split), each defaulting to the dev group.
|
|
# EXTRA VARS ONLY: a play's `hosts:` is templated before any host exists, so
|
|
# group_vars cannot be read there. Prod: `-e k3s_hosts=k3s_prod` etc.
|
|
# * WHICH GROUP A ROLE MEANS BY "MY PRIMARY"/"MY SERVERS" — `k3s_primary_group` /
|
|
# `k3s_servers_group`, set in group_vars/all.yml (dev) and group_vars/k3s_prod/vars.yml
|
|
# (prod), so roles resolve their own environment with NO per-run flag — the same
|
|
# mechanism k3s_api_host already used.
|
|
# Running with no extra vars is byte-for-byte the dev behaviour it always had. See
|
|
# infra/ansible/README.md "Targeting prod" and PROD-PROVISIONING.md §6.
