claude-bot d15a4654a0 perf(grafana-db): raise archive_timeout to 30min on gf-pg
ci/woodpecker/pr/ci-scripts-test Pipeline was successful
ci/woodpecker/pr/ci-manifests-test Pipeline was successful
ci/woodpecker/pr/pr-review Pipeline was successful
A WAL segment is a fixed 16 MiB file. archive_timeout forces a segment
switch on a timer so the archive never trails reality by more than that
interval, and the switched-out segment is written and archived at its full
16 MiB no matter how few bytes of real WAL it holds. CNPG defaults this to
5min, which permits up to 288 segments/day = 4.6 GB/day per cluster.

Measured on gf-pg: the database is 21 MB and generates 4.5 MB/day of actual
WAL, while its RBD volume takes 211 MB/hour -- against 192 MB/hour predicted
from 12 switches of 16 MiB. Essentially every byte written to this volume is
padding, roughly 1100x amplification.

This resolves an anomaly that has been open since the start of the endurance
work: gf-pg appeared to write gigabytes per day for a 21 MB database, and
neither WAL volume nor data changes could account for it. Segment padding
does, exactly.

Applied to gf-pg alone as a staged rollout. It is the lowest-risk cluster
and gives the cleanest signal -- its real WAL is small enough that any change
in volume is unambiguously attributable to this parameter. The same default
affects all seven clusters and is worth an estimated ~24 GB/day of logical
writes fleet-wide, but that only goes ahead once this one is verified.

The cost is RPO. On total loss of the cluster, up to 30min of Grafana state
becomes unrecoverable instead of 5min. That state is dashboards, annotations
and preferences, changing at ~4.5 MB/day, so the window is nearly always
empty. Clusters holding credentials or job state get evaluated separately
rather than inheriting this value by default.

archive_timeout is in CNPG's GlobalDefaultSettings, not its
FixedConfigurationParameters, so it is user-overridable -- verified against
pkg/postgres/configuration.go rather than assumed.

Context: drive-endurance work on three QLC NVMe OSDs at 81-87% wear.

# Runbook — converting a control-plane node from Proxmox VM to bare metal
Converts one MS-01 from "Proxmox host running a Talos VM" to "Talos on bare
metal", and swaps its Ceph OSD onto a Samsung PM983 at the same time. Written
after doing jupiter on 2026-08-25; saturn and neptune remain.
Everything here that reads like an over-specific warning is something that
actually happened. The conversion itself is straightforward — the failures were
all in state that outlived the VM.
## What the node ends up as
| | |
|---|---|
| System disk | Kingston OM8PGP41024Q-A0, selected by serial |
| EPHEMERAL (`/var`) | the retired Crucial P3, selected by serial |
| Ceph OSD | Samsung PM983, selected by `/dev/disk/by-id` |
| Management | VLAN 40 tagged on X710 port 0 |
| v30iot | VLAN 30 on the same port, named `ens19` |
| Ceph cluster net | X710 port 1, `10.99.0.x/29`, MTU 9000 |
## Before you start
- [ ] All three OSDs up, all mons in quorum, PGs `active+clean`. Do not start
from a degraded cluster; the window itself removes one of three.
- [ ] Cluster fits on two nodes. Check `kubectl describe node` allocation on the
two survivors. Take immich down (`kubernetes/apps/immich`, both
Deployments to `replicas: 0`) — it frees ~1000m against a shortfall of
roughly 200m and takes its image pulls off the remaining nodes.
- [ ] `cephfs-metadata` to size 2 / min_size 1 for the duration. At size 3 on
two hosts every PG is undersized with min_size 2, so one further OSD loss
blocks IO on every CephFS mount cluster-wide.
- [ ] Talos metal ISO on a USB stick. Schematic
`a21cec8f35ae32ab5e9a452e7b13500ca8776053930b8e182b9cb23eed186b64`
(`net.ifnames=1`, intel-ucode, thunderbolt; no qemu-guest-agent).
Verify by comparing partition offsets and sizes against the ISO with
`fdisk -l` — blkid labels lie after a rewrite.
- [ ] Physical access. Secure Boot must be turned off (see below), and that is
the one step nothing can do remotely.
## 1. Evacuate the OSD
```sh
ceph osd out <id>
```
Wait until no PGs are `backfilling` or `backfill_wait`. Do **not** wait for
`ceph osd safe-to-destroy` — pools at size 3 keep the OSD in their acting set
because three copies cannot be placed on two hosts, so it never returns clean.
Then remove it. The node must already be out of `cephcluster.yaml`'s
`storage.nodes` list, or the operator rebuilds the OSD within one reconcile and
starts backfilling onto the drive you are about to pull:
```sh
kubectl -n rook-ceph scale deployment rook-ceph-osd-<id> --replicas=0
ceph osd purge <id> --yes-i-really-mean-it
kubectl -n rook-ceph delete deployment rook-ceph-osd-<id>
```
## 2. Drain, and leave the cluster
```sh
kubectl drain <node> --ignore-daemonsets --delete-emptydir-data --timeout=300s
```
Single-replica workloads with `minAvailable: 1` PDBs will refuse eviction — that
is deliberate, they exist to surface the pod rather than let it be yanked. On
this cluster that is `influxdb-influxdb2-0`, `woodpecker-server` and the
CNPG primary. Move each one deliberately with `kubectl delete pod`; they
reschedule onto the survivors and their RBD volumes follow.
```sh
talosctl -n <node> reset --graceful --wipe-mode system-disk
kubectl delete node <node>
```
`--wipe-mode system-disk` and not the default `all`: the OSD drive is being
pulled anyway and wiping a terabyte of it is wasted time. `--graceful` leaves
etcd cleanly. Delete the Node object — it carries the `unschedulable` flag from
the drain, which the rebuilt node would otherwise inherit.
## 2a. Destroy the VM in OpenTofu — while the host is still a PVE node
Remove `opentofu/vm_15N_k8s_N.tf`, then apply. This **must** happen before the
host leaves the Proxmox cluster: afterwards the provider cannot reach the node,
the plan errors, and the only escape is `tofu state rm`, which is off the table.
Point `proxmox_api_url` at a host that will *survive* the conversion, not the one
being converted.
Manual triggers are currently broken by the Woodpecker v3.18.0 regression
(issue #582). Until that is resolved, run it locally:
```sh
AWS_ACCESS_KEY_ID=… AWS_SECRET_ACCESS_KEY=… AWS_REGION=fsn1 \
tofu -chdir=opentofu init -backend-config=<file>
… plan -target=module.k8s_N -var-file=<file> -out=<plan>
… apply <plan>
```
The `AWS_*` environment variables are required *in addition to*
`-backend-config`, or the S3 backend fails `HeadObject` with 403 even with
credentials that can read the object fine via the aws CLI.
## 2b. Proxmox quorum — matters from the second conversion onward
Two nodes remain after jupiter, with `expected_votes: 2` and quorum 2. Removing
one leaves the last node inquorate and `/etc/pve` read-only, which blocks the
final VM destroy. On the surviving node:
```sh
pvecm expected 1
```
This is the official recovery. Proxmox documents it in the storage replication
chapter (`/usr/share/pve-docs/chapter-pvesr.html`), verbatim:
> If you have no quorum, we strongly advise to fix this first and make the node
> operable again. Only if this is not possible at the moment, you may use the
> following command to enforce quorum on the current node: `# pvecm expected 1`
The caveat there is about restoring the missing node instead. Here the missing
node is deliberately gone for good, so enforcing quorum is the correct branch
rather than a workaround.
Run it only once the node is actually alone — attempting it while both nodes are
up fails with `CS_ERR_INVALID_PARAM`, since corosync will not set expected votes
below the members it can currently see. Which is exactly why it becomes valid
when one remains.
Runtime only; it does not survive a reboot, so re-run it if the survivor
restarts before its own conversion.
## 3. Hardware
Power the host off, then:
1. Kingston boot drive out of slot 1, into slot 2.
2. Crucial P3 out of slot 2 — it becomes EPHEMERAL, so put it in slot 3 rather
than setting it aside.
3. Slot 1 switch to **U.2**. Set it before the drive goes in; there is nothing
to record afterwards, the installed drive type implies the position.
4. PM983 onto the included 7mm M.2-to-U.2 adapter, into slot 1.
Boot the host's existing PVE once before touching Talos and check the drive:
```sh
nvme smart-log /dev/nvmeXn1 | grep -iE 'percentage_used|media_errors|critical'
nvme id-ns /dev/nvmeXn1 -H | grep -i 'in use' # want 512b data, 0 metadata
wipefs /dev/nvmeYn1 # Crucial: clear the old bluestore sig
ip link set <ceph-port> up && ethtool <ceph-port> | grep -i 'link detected'
```
This is the last revert point. A bad drive here means the Crucial goes back and
the VM is recreated from tofu with nothing lost. Once Talos writes to the
Kingston, PVE on that host is gone.
Relocating the boot drive is safe: `rpool` is referenced by NVMe EUI and the
UEFI entries by GPT PARTUUID, neither of which encodes a slot.
## 4. Secure Boot
MS-01 ships with Secure Boot on, and Proxmox satisfies it with a
Microsoft-signed shim. The Image Factory `metal-amd64.iso` is an unsigned UKI
and the firmware rejects it outright. **Turn Secure Boot off in the BIOS.**
A signed variant exists per schematic, but it is signed with SideroLabs' key
which firmware does not trust by default, and the installed system would have to
use the secureboot installer image too. That is a separate project.
## 5. Install
Boot the stick. Maintenance mode DHCPs untagged on every link; on these hosts
that lands on `192.168.8.x`, which is routable from the workstation. It DHCPs on
*every* link, so one machine answers on several addresses at once — they are the
same host, not several hosts. `get disks` on each confirms it.
Maintenance mode does serve `talosctl get`. `--insecure` is a flag on the
subcommand rather than a global, so it must come *after* `get` — placed before
it, cobra resolves to the legacy `talosctl disks` command and reports
`unknown flag: --insecure`:
```sh
talosctl -n <maintenance-ip> get disks --insecure
talosctl -n <maintenance-ip> get links --insecure
```
Verify serials and MACs here, on the machine itself, against the config about to
be applied.
Build the config from the **live cluster's secrets**, not a fresh
`talosctl gen config`, or the node forms a new cluster instead of joining:
```sh
talosctl -n <surviving-node> get mc v1alpha1 -o jsonpath='{.spec}' > cp.yaml
talosctl gen secrets --from-controlplane-config cp.yaml -o secrets.yaml
talosctl gen config homelab https://k8s.renner.uno:6443 \
--with-secrets secrets.yaml --output-types controlplane \
--config-patch @talos/patches/cluster.yaml \
--config-patch @<cilium additive half> \
--config-patch @talos/patches/registry-mirror.yaml \
--config-patch @talos/patches/k8s-N.yaml -o install.yaml
```
Confirm `cluster.id` matches the running cluster before applying.
Strip the generated `HostnameConfig` document — it collides with
`machine.network.hostname` from the per-node patch. `bootstrap.sh` does the same.
`cilium-cni.yaml` cannot be passed whole: its `$patch: delete` document fails
against a base with no `inlineManifests` (issue #581). Use only the additive
second document.
Validate:
```sh
talosctl validate --config install.yaml --mode metal
```
### Install minimal, complete on the running node
Do **not** apply the full per-node config in maintenance mode. A document that
references an interface which does not exist yet hangs the install: the node
sits at `STAGE: Installing` indefinitely with `KUBELET n/a`, `APISERVER n/a`,
and the console scrolling
```
k8s.NodeApplyController: error getting node: nodes "k8s-N" not found
```
That message is a symptom of an install that never finished, not a Kubernetes or
networking fault — the node holds a DHCP address and is reachable throughout. On
saturn the offenders were the `ens19` VLAN document and the sysctl naming it,
`net.ipv6.conf.ens19.disable_ipv6`. Three cold installs hung on it; the identical
config applied cleanly once the node was up. Wiping disks makes no difference —
it is not leftover state.
**Stage 1** — the smallest config that installs and joins, plus `EPHEMERAL`,
which is one-shot (section 7) and so cannot be deferred to stage 2:
```
machine.network.hostname, machine.install.diskSelector, certSANs, nodeLabels
LinkConfig <uplink>
VLANConfig mgmt0
DHCPv4Config mgmt0
VolumeConfig EPHEMERAL
```
```sh
talosctl apply-config --insecure -n <maintenance-ip> --file install-stage1.yaml
```
**Stage 2** — once the node is `Ready` and `talosctl etcd members` lists it,
apply the full config to the running node. `--mode=try` reverts on its own if the
network config is wrong, so it cannot strand the node; re-apply with
`--mode=auto` to persist.
```sh
talosctl -e <node-ip> -n <node-ip> apply-config --mode=try --timeout=3m --file install.yaml
talosctl -e <node-ip> -n <node-ip> apply-config --mode=auto --file install.yaml
```
Both applied without a reboot on saturn. Confirm `ens19`, `mgmt0` and the Ceph
link are up afterwards with `talosctl get links` and `get addresses`.
## 6. The network config will strand the node if it is wrong
Talos stops running default DHCP operators **for the entire machine** as soon as
a single new-style network document exists — the gate is presence of a document,
not success of resolution. If the configured path fails to materialise there is
no fallback on any interface, and recovery needs a console and install media.
Concretely: do not use `LinkAliasConfig` as a `VLANConfig` parent without
verifying it. Aliases *are* supported (confirmed in v1.12.6 source and by a
maintainer), but a selector matching zero links is skipped **silently**, and
`permanent_addr` comes from an ethtool ioctl with no fallback — if the driver
does not answer, the match is against an empty string and everything downstream
that references the alias does nothing.
Address links by predictable kernel name. To introduce aliases later, do it on a
node that is already up, with `talosctl apply-config --mode=try --timeout=5m`,
which rolls back on its own, and check `talosctl get linkaliasspec`.
Interface names derive from PCI topology and are stable — but not immune.
Adding a third NVMe to jupiter renumbered the buses and renamed the unused
second I226 from `enp89s0` to `enp90s0`.
## 7. EPHEMERAL placement is one-shot
```yaml
apiVersion: v1alpha1
kind: VolumeConfig
name: EPHEMERAL
provisioning:
diskSelector:
match: disk.serial == '<crucial serial>'
minSize: 50GiB
grow: true
```
Talos applies volume configuration **only when the volume does not yet exist**.
Applied afterwards it is silently ignored, and relocating EPHEMERAL then needs a
disk wipe and a fresh boot from install media. It must be in the first
`apply-config`.
Match by serial. `disk.transport == 'nvme' && !system_disk` matches the PM983 as
well, and losing that coin flip formats the OSD drive.
Verify afterwards:
```sh
talosctl -n <node> get volumestatus EPHEMERAL -o yaml | grep -E 'location|phase'
talosctl -n <node> get disks
```
## 8. The mon will not come back on its own
**This is the step that cost the most time on jupiter.** The rebuilt node has a
new MAC and therefore a new DHCP lease, but Ceph has its mon pinned to the old
address in three places. The mon cannot bind an address the host no longer has,
so it crashloops; the operator then tries to restart a *healthy* mon as its next
step, Ceph refuses because that would drop quorum, and it retries every 60
seconds forever without ever reaching the storage reconcile. Nothing else
progresses behind it.
Fix in this order — the order matters, because doing it the other way round has
the operator faithfully recreate the mon from the stale ConfigMap:
```sh
# 1. ConfigMap first
kubectl -n rook-ceph edit cm rook-ceph-mon-endpoints
# remove the dead mon from `data` and from `mapping`
# 2. then the monmap
ceph mon remove <id>
# 3. then the deployment — check it really carries the old address
kubectl -n rook-ceph get deploy rook-ceph-mon-<id> -o yaml | grep public-addr
kubectl -n rook-ceph delete deploy rook-ceph-mon-<id>
```
Rook then creates a **new** mon with the next free ID (jupiter's `c` came back
as `d`), on the correct address. It does not repair the old one.
Note mons use host ports under `network.provider: host`, so a replacement mon
cannot schedule while the broken one's deployment still holds 3300/6789 — the
canary sits `Pending` with "didn't have free ports" until the old deployment is
deleted.
## 9. Re-add the OSD
Add the node back to `cephcluster.yaml` under `storage.nodes`, naming the PM983
by `/dev/disk/by-id`:
```yaml
- name: k8s-N
devices:
- fullpath: /dev/disk/by-id/nvme-SAMSUNG_MZQLB960HAJR-00007_<serial>
```
**Not** a bare device name. Talos enumerates these drives in a different order
than Proxmox did — on jupiter `nvme0n1` is the Kingston *system* disk, and the
PM983 is `nvme2n1`. Rook would probably decline a partitioned system disk, but
that is luck rather than design.
Get the path from `talosctl -n <node> get disk <dev> -o yaml`, under `symlinks`.
## 10. Verify and restore
```sh
kubectl get nodes # Ready
talosctl -n <node> etcd members # 3 members
ceph status # 3 mons in quorum, 3 osds
ceph osd tree # OSD under the right zone/host
ceph device ls # PM983 backing the new OSD
```
Then undo the window changes: `cephfs-metadata` back to size 3, immich back to
1 replica, and `ceph config set osd osd_mclock_profile balanced` if it was
raised to `high_recovery_ops` to speed the evacuation.
The retired Crucial leaves a stale entry in `ceph device ls`. Remove it with
`ceph config-key rm device/<devid>`; the mgr's devicehealth view may lag.
## Known-stale things that will bite
- `bootstrap.sh` cannot generate a config at all right now (issue #581), so a
cold rebuild is broken independently of this work.
- Manual Woodpecker pipelines are broken (issue #582), so anything gated on
`PIPELINE == "..."` must be run another way.
- Cilium's eBPF datapath silently drops VLAN-tagged traffic unless
`bpf.vlanBypass` is set. Both `mgmt0` and `ens19` are VLAN interfaces on a
converted node. Not observed on jupiter, but it is the first place to look if
the v30iot macvlan workloads misbehave there.

- drops `siderolabs/qemu-guest-agent`, which has nothing to talk to on bare metal
- adds `siderolabs/intel-ucode`, since no hypervisor is supplying microcode now
- adds `siderolabs/thunderbolt`, unused so far and inert until
`machine.kernel.modules` requests `thunderbolt`/`thunderbolt_net`. It is
present only so enabling the MS-01 Thunderbolt mesh later does not require a
new image and a reinstall. Note its udev rule auto-authorises any Thunderbolt
device attached to the machine once those modules are loaded.

# WS90 Zigbee reporting configuration
Records the ZCL attribute-reporting configuration applied to the Wetterstation
(Ecowitt WS90 powered by Shelly, IEEE `0xc02cedfffe958f40`) and how to restore
it, because **this configuration lives on the device and in Z2M's
`database.db`, not in git**. Zigbee2MQTT has no settings-schema field for
reporting configuration, so there is nothing declarative to reconcile — Flux
cannot restore it and a fresh PVC will not have it.
## Applied configuration
Endpoint 1, all intervals in seconds. `change` is in the attribute's raw ZCL
units; the physical deadband is `change ÷ scale`.
| attribute | cluster | min | max | change | deadband | converter default |
| --- | --- | --- | --- | --- | --- | --- |
| temperature | `msTemperatureMeasurement` (1026) | 5 | 3600 | 10 | 0.1 °C | 10 / 3600 / 100 |
| humidity | `msRelativeHumidity` (1029) | 5 | 3600 | 50 | 0.5 % | 10 / 3600 / 100 |
| pressure | `msPressureMeasurement` (1027) | 5 | 3600 | 1 | 1 hPa | 10 / 3600 / 50 |
| illuminance | `msIlluminanceMeasurement` (1024) | 5 | 3600 | 5 | 5 lx | 10 / 3600 / 5 |
| windSpeed | `shellyWS90Wind` (0xfc01/0) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
| windDirection | `shellyWS90Wind` (0xfc01/4) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
| gustSpeed | `shellyWS90Wind` (0xfc01/7) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
| uvIndex | `shellyWS90UV` (0xfc02/0) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
| rainStatus | `shellyWS90Rain` (0xfc03/0) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
| precipitation | `shellyWS90Rain` (0xfc03/1) | 5 | 3600 | 1 | — | 10 / 3600 / 1 |
`genPowerCfg.batteryVoltage` (cluster 1, attribute 33) is deliberately left at
its hourly default.
The three `shellyWS90*` clusters are manufacturer-specific and require
`"options": {"manufacturerCode": 5264}` on every reconfiguration request.
## Why min is 5 and not 10
The station transmits every 8.8 s. `min` is a hold-off: a change-triggered
report is held until at least `min` seconds after the previous one. With
`min: 10` every report was therefore held past a transmit cycle and landed on
the next, so attributes reported at best every 17.6 s and drifted out of phase
with each other — the published stream showed no 8.8 s periodicity at all,
just a smear across 2–8 s.
At `min: 5` each attribute reports on its own transmit. The MQTT stream then
carries one publish per transmit cycle, measured at a mean gap of 8.69 s.
Total publish volume *fell* (~631/h to ~445/h) because each publish now
carries a whole cycle instead of a fragment of one.
Any value below 8.8 s achieves this. 5 leaves margin without approaching the
cycle time.
## Why the deadbands differ from the converter defaults
The defaults come from the shared `modernExtend` helpers in
zigbee-herdsman-converters (`m.temperature()`, `m.pressure()`, `m.humidity()`,
`m.illuminance()`), which the WS90 definition in `shelly.ts` composes without
overrides. They are anti-chatter values sized for battery-powered indoor
sensors, where report volume costs coin-cell life and mesh airtime. This
station is mains-and-solar and exists to resolve small changes, so the
trade-off runs the other way.
Each value above is matched to the resolution the device actually reports:
temperature and pressure arrive in 0.1-unit steps, humidity in whole percent.
Pressure is worth calling out. The converter default of `change: 50` with
`scale: 10` is a 5 kPa (50 hPa) deadband, which real barometric pressure never
traverses — so pressure only ever updated on the hourly `max` heartbeat, and
`pressure_trend` and `weather_condition` were derived from that. The same
library's older `reporting.ts` helper configures the identical ZCL attribute
with `change: 5`, a 5 hPa deadband, so the two code paths disagree by 10× and
the modernExtend value is the outlier.
## When this is lost
Anything that makes Z2M re-run `configure` on the device overwrites all of it
with the converter defaults:
- re-pairing or re-joining the device
- an explicit `zigbee2mqtt/bridge/request/device/configure`
- a converter update that changes the definition and triggers reconfiguration
It also will not exist on a fresh PVC. Re-apply with the commands below.
## Re-applying
Published from the `discovery-guard` sidecar, which already holds the
`zigbee2mqtt` broker credential (ACL `readwrite zigbee2mqtt/#`, which covers
`bridge/request/#`) so no credential has to leave the cluster:
Ten separate requests, one per attribute — written out literally rather than
generated by a shell helper, because the nested quoting through `kubectl exec
-- sh -c` is where this goes wrong. Each line below is in the exact form that
was executed and verified.

```
These are idempotent — re-sending a request that matches the current
configuration is a no-op on the device.
The device must be awake and reachable; each request performs a real
`ConfigureReporting` exchange and fails if it is not.
## Verifying
Read back what the device actually accepted — Z2M records the negotiated
result, so this reflects the device, not the request:
```sh
kubectl exec -n home-assistant "$POD" -c zigbee2mqtt -- \
grep 0xc02cedfffe958f40 /app/data/database.db |
jq -r '.endpoints | to_entries[] | .value.configuredReportings[]?
| "cluster=\(.cluster) attr=\(.attrId) min=\(.minRepIntval) max=\(.maxRepIntval) change=\(.repChange)"'
```
All ten rows above should read `min=5 max=3600`. On the wire, the publish
cadence on `zigbee2mqtt/Wetterstation` should sit at ~8.7 s and temperature
should move in 0.1 °C steps; 1 °C steps mean the defaults are back.
## Making it durable upstream
The lasting fix is for the WS90 definition to pass explicit `reporting`
overrides rather than inherit indoor-sensor defaults, which would fix every
WS90 rather than this one. `m.temperature()` and the other helpers already
accept a `reporting` argument. The pressure divergence between
`modernExtend.ts` and `reporting.ts` is a separate upstream bug worth
reporting on its own.

# That drive is at 87% of its rated endurance and was this node's Ceph OSD until
# the PM983 replaced it. /var is exactly the right role for a disk in that
# state: containerd's image and snapshot store, pod logs and the Ceph mon store
# are all reconstructible, so the drive is consumable here in a way it is not as
# an OSD. It also gives /var ~931 GB instead of the 64 GB the VM-era zvol had,
# which is the constraint that makes k8s-2 and k8s-3 trip DiskPressure whenever
# they absorb another node's pods.
#
# THIS ONLY TAKES EFFECT ON FIRST PROVISION. Talos applies volume configuration
# solely when the volume does not yet exist; a config applied after EPHEMERAL
# has been created elsewhere is silently ignored, and relocating it then
# requires wiping the disk and booting install media again.
#
# Matched by serial deliberately. `disk.transport == 'nvme' && !system_disk`
# would match the PM983 as well, and losing that coin flip means Talos formats

# X710 port 0 carries the switch trunk. It takes no addressing itself — the

# business being on — so management and v30iot both ride it as tagged VLANs.
#
# Links are addressed by predictable kernel name. Those derive from PCI
# topology, not probe order — though not immune: adding the third NVMe
# renumbered the buses and moved the unused second I226 from enp89s0 to
# enp90s0. Neither name used here was affected.
#
# LinkAliasConfig would be the better way to pin these, and is worth
# reintroducing — but only once it is proven. Aliasing both X710 ports by
# permanent MAC and using the aliases as VLAN parents produced a node with no
# address on any interface: the aliases were never created, so every document
# referencing them did nothing, including the static address on port 1. Verify
