Hardware inventory + hardware-stats gathering: pick the first 3–5 cluster machines #1810
Description
Relocated from dezren39/darwin-nix#501 on 2026-10-28 - it was filed in the wrong repo; developing-today/code is its home. Original content follows, verbatim.
Problem
We have ~12 basement Threadripper machines and no per-machine records. We cannot choose the first 3–5 Talos/Cozystack cluster nodes — or keep them at parity — until we know exactly what each box contains. Drew's directive: gather all hardware stats first, so the cluster starts with the best / most-identical machines.
Source: idea register 2026-10-20 (goal stand-up-lab-cluster-talm-talos-cozystack-postgres-rustfs).
What we know
- Core machines are the same motherboard, same CPU, same specs except SSDs; ≥3 TB DDR4 server ECC RAM across the fleet.
- 15–16 × 16 TB helium WD server-pull HDDs; every machine has some NVMe boot drive (best: Samsung 990 Pro); fast NVMe tier is "all 990s", mid tier mixes 980s / smaller 990s / good consumer SSDs.
- Core machines have enterprise BMC/IPMI ("ASM") with KVM; NIC spec on core machines is unconfirmed ("at least 200 Gb ports" as dictated — exact spec TBD here).
- GPUs are not a resource (3× Intel B50, 1× RTX 2060, old display-only cards) — record them, don't plan around them.
- Blockers: basement power capacity and mess — full-fleet power-on is a long tail, so stats gathering must work machine-by-machine, including via BMC without a full boot where possible.
Acceptance / first steps
- Define the per-machine record schema: motherboard, CPU, RAM (total + DIMM layout), every SSD/HDD (model, size, firmware, SMART/health, wear), NICs (model, speed, ports), BMC/KVM IP, BIOS version, BMC firmware version, PSU(s), GPU.
- Gather stats for all ~12 machines (BMC/Redfish/iKVM where possible; minimal boot media otherwise) and store the records in this repo (or the goal's files/) in a diffable text format.
- Produce a ranked shortlist of the first 3–5 cluster nodes: parity of disk size/capability first (3 hosts × 4× 16 TB for the HDD tier; matching NVMe tiers), then health.
- Pin down the exact NIC spec and the switch gear between core machines (feeds the LINSTOR/DRBD design issue).
Open questions
- Exact NIC spec / switch hardware (register open question 5).
- Are all 15–16 HDDs healthy enough for RAID 10 pools, or are some spares-only?
Acceptance criteria
- A per-machine hardware inventory exists (linked from this issue) for the ~12 basement machines: CPU, motherboard, RAM, and especially SSD/drive details per box.
- The first 3–5 cluster machines are picked from that inventory, with the parity reasoning recorded.
- The inventory is in a form that can be re-gathered/refreshed, not a one-off prose list.

Intake review
🤖 Fleet monitor intake pass (protocol §5).
Related: the 2026-10-20 lab-cluster idea register (linked in the body); this inventory gates dezren39/darwin-nix#503 (TALM per-node config) and dezren39/darwin-nix#504 (storage tiers); sibling issues dezren39/darwin-nix#502, dezren39/darwin-nix#505.
Live check: still open and unlabelled at intake; no merged PR resolves it — the body states there are no per-machine records yet.
Notes / risks: machines are stated identical except SSDs, so drive details are the discriminating data; an inventory that skims drives will not support the node pick.
Suggested approach: gather stats first (as Drew directed in the body), publish the inventory, then record the 3–5 node pick — several sibling cluster issues sequence behind this one, so it is the highest-leverage of the set.

Superseded by #1080 (hardware inventory & first-node selection epic)
The basement cluster program was seeded into its standard structure on 2026-10-26 (roadmap + epics + sub-issue tasks in developing-today/code, all in org Project #4 as Area=lab-cluster). Do not start work from this issue - work is tracked at #1080 (hardware inventory & first-node selection epic). Full mapping is on nixdezren39/nix#508. Left open for Drew to close as superseded.

agent-note:v1
state: triaged (coverage pass)
Coverage pass 2026-11-03: reviewed in the fleet-wide per-issue pass (drift / overlap / already-handled / stale / blockers / ordering). Verdict: still live; queued in repo-health-code-pilot as triage at priority 40 (priority/normal). If this is already handled at current main, the triage closes it with evidence; if it needs splitting, the triage files the split.

Revalidated issue #1810 as OPEN. Its existing 2026-10-27 note explicitly says it is superseded by #1080 and instructs not to start work here. #1080 is still OPEN and its latest triage identifies the genuine physical-access blocker; task 7624 is already blocked/escalated for that decision. No relevant PR supersedes or resolves this work. Task 7743 completed as superseded; #1810 is now an informational pointer to #1080, not an independent work item.
