Julien LutranandClaude Fable 5 79ad1b7179 Document the ks2 decommission plan and the new ks4 backup legs
- ks2/: decommission plan with release gates (rental ends Sep 30),
  nuc-seed and final-decommission runbooks

  full-resend caveat when refreshes lapse past snapshots.expiry
- ks4/plakar-s3-data.md: plakar direct-to-S3 leg (auto-discovered DB
  dumps incl. grants/globals, fs sources, exclude list, restore test)
- ks4/plakar-incus-integration.md: design + scaffold status of the
  plakar incus importer
- README.md: index ks2/, update the ks4 durability bullet

Personal infrastructure notes.
- [`nuc/`](nuc/) — home lab on `nuc` (see below)
- [`ks4/`](ks4/) — prod server `ks4` at OVH (see below)
- [`ks2/`](ks2/) — legacy backup server being decommissioned
(rental ends Sep 30, 2026): [plan](ks2/plan.md)
- [`archer-c7/`](archer-c7/) — home router (TP-Link Archer C7 v5,
OpenWrt, `192.168.0.2`, WAN = phone USB tether):
[upgrade to 25.12](archer-c7/upgrade-openwrt-25.12.md)
## Homelab: nuc
Incus host on the LAN.
- Host: `nuc``192.168.0.3`, Debian 13, Intel Alder Lake-N
(iGPU `i915`, shared by both Jellyfin containers) —
bare-metal reinstall: [nuc/nuc-install.md](nuc/nuc-install.md)
- SSH: `ssh -i id_rsa_claude root@192.168.0.3` (keys at repo root, gitignored)
- Instances are bridged onto the LAN (192.168.0.0/24)
- USB 4 TB WD Red: ZFS pool `usb4t``usb4t/backup``/backup`
(incus exports, `nuc/` + `ks4/` subdatasets, 1 TB quota) and
`usb4t/media``/srv/media` (media library, shared into containers
via `shift=true` disk devices; works because ZFS ≥ 2.2 supports
idmapped mounts)
- NAS: `//192.168.0.10/Shared` (CIFS) — original media source, normally
offline; not mountable into containers (idmapped mounts unsupported
on CIFS)
- Backups: all local instances replicated to the USB pool
(`/root/scripts/incus-copy.sh -p backup -s nucbackup`; replicas
stopped, autostart off) — see
[nuc/nuc-install.md](nuc/nuc-install.md); ks4 replicas pulled into
pool `ks4backup` — see [ks4/incus-copy.md](ks4/incus-copy.md)
### Instances
| Name | IP | Doc | Features |
|---|---|---|---|
| [jellyfin-server](nuc/jellyfin-server.md) | 192.168.0.5 | ✅ | unprivileged, autostart; iGPU render node (`gpu` device, render gid) for QSV/VAAPI transcoding; `/srv/media` disk device (`shift=true`); proxy device → host :8096 |
| [jellyfin-client](nuc/jellyfin-client.md) | 192.168.0.6 | ✅ | **privileged**, autostart; full iGPU (`gpu` device, gid 44) → HDMI kiosk (cage + Jellyfin Media Player); custom `raw.lxc` (bind `/dev/snd`, `/dev/input`, host `/run/udev`); Pioneer USB audio as ALSA default; FR keymap; go-librespot Spotify Connect ("Pioneer A-70") |
| [transmission-bt](nuc/transmission-bt.md) | 192.168.0.7 | ✅ | unprivileged, autostart; always-on WireGuard full tunnel → ks4 (egress = 193.70.35.17, kill switch: no default route); `/srv/media` disk device (`shift=true`), downloads to `/media/downloads`; web UI :9091 (LAN only) |
| blocky | 192.168.0.254 | — | unprivileged, autostart; DNS ad-blocker |
| privoxy | 192.168.0.11 | — | unprivileged, autostart; filtering HTTP proxy |
| homeassistant | (stopped) | — | **virtual machine**, 50 GiB root disk on pool `data` |
## Prod: ks4
Incus host at OVH — public-facing self-hosted services.
- Host: `ks4.lutran.fr``193.70.35.17`, **SSH on port 2233**,
Debian 13, Xeon D-1521 / 32 GiB, 2× 6 TB (OS on mdraid RAID1,
ZFS pool `data` on `sda5`) — setup & rebuild:
[ks4/install.md](ks4/install.md)
- SSH: `ssh -i id_rsa_claude -p 2233 julien@193.70.35.17`
(`julien` has passwordless `sudo incus …`)
- Instances are on a NAT bridge `incusbr0` (192.168.1.0/24); public
ingress via Incus proxy devices. `gateway` (nginx) is the sole HTTP/S
entry point and fans out to the app containers.
- Services: gateway, mail, nextcloud, seafile, git, freshrss, bitwarden,
outline, login (SSO), wireguard, + more — full table in
[ks4/install.md](ks4/install.md).
- ⚠️ The ZFS `data` pool is single-disk (not mirrored); durability
rests on nightly root cron jobs — 01:00 `incus copy --refresh` of
all instances to the local `backup` pool on sdb5
([ks4/local-backup-cron.md](ks4/local-backup-cron.md),
[ks4/incus-copy.md](ks4/incus-copy.md)), 04:30 plakar backups
(DB dumps + data trees) to S3
([ks4/plakar-s3-data.md](ks4/plakar-s3-data.md)), plus during the
transition a 04:00 rsync stopgap to ks2
([ks2 decommission plan](ks2/plan.md)); a pull leg to nuc pool
`ks4backup` awaits FTTH.

phones/laptops: WG peers 10.8.0.2-3 reach 192.168.1.x through the same endpoint
```
Both tunnels initiate **from** nuc (home NAT, dynamic IP) toward ks4's
fixed endpoint; ks4's incus API is never exposed to the internet.
### Conventions
- One markdown file per instance in `nuc/`, containing the full
install script (idempotent-ish, run as root on the host), first-run
configuration, and troubleshooting notes.
- Containers are built from `images:ubuntu/24.04` and configured
exclusively through `incus exec`/`incus config` so the doc is the
single source of truth — rebuilding = re-running the script.
