Builds the box that ends the usb4t dropouts: the JMicron bridge was the least reliable device in the setup and it held the intended off-site copy of ks4. The 4 TB now sits on direct SATA as pool `tank`. - OS on mdraid RAID1 across two 120 GB SSDs (Intel 330 + Toshiba Q300), both ESPs bootable; `incus` ZFS mirror on their tails, ~22% left unallocated as over-provisioning - media at /export/media, exported read-only over NFSv4 to nuc - transmission-bt moves here (its WireGuard tunnel is in-container, so ks4 needed no change) and writes to the dataset locally - backup pools nucbackup / ks4backup / nasbackup - monitoring live: msmtp (submission+auth, verified 250), zed with NOTIFY_DATA, zpool-health.sh every 15 min, smartd on all three disks Traps recorded because none of them point at their own cause: booting with the display active kills the i915 probe and wedges incus; d-i picks grub-pc vs grub-efi from how the installer booted; `incus storage create` hangs forever on a mountpoint=none dataset; the BMC is deliberately never cabled, so there is no out-of-band console.

# Storage: nas
|
|
|
|
Storage + backup host on the LAN, added 2026-08.
|
|
|
|
- **Always-on host.** nuc is now an on-demand media box (see
|
|
[nuc/README.md](../nuc/README.md)), so everything that must stay up —
|
|
LAN DNS, the HTTP proxy, torrents — lives here.
|
|
- Debian 13, Supermicro **A1SAi-2750F** / Intel Atom C2750 (8 c, 20 W,
|
|
ECC DDR3) — build procedure: [nas-install.md](nas-install.md)
|
|
- SSH: `ssh -i id_rsa_claude root@192.168.0.4`
|
|
- **No iGPU** (Avoton is headless; video is the AST2400 BMC). Anything
|
|
needing hardware transcoding stays on nuc.
|
|
- Pools:
|
|
- `incus` — ZFS mirror across the last partition of both 120 GB SSDs;
|
|
holds this host's container roots. OS itself is on mdraid RAID1 +
|
|
ext4 across the same disks (rationale in
|
|
[nas-install.md](nas-install.md) §2).
|
|
- `tank` — the 4 TB WD Red, **on direct SATA**. This is the whole
|
|
point of the box: the disk used to hang off a JMicron USB bridge on
|
|
nuc that suspended the pool 61 times in 30 days
|
|
([nuc/usb4t-dropouts.md](../nuc/usb4t-dropouts.md)). Single vdev,
|
|
accepted — nothing on it is irreplaceable.
|
|
- `tank/media` → `/export/media`: the media library. Exported
|
|
**read-only over NFSv4 to nuc**, where `jellyfin-server` reads it;
|
|
written locally only by `transmission-bt`.
|
|
- Backups: nuc ↔ nas **cross-replication** (each host's instances live
|
|
on the other), plus the ks4 pull leg —
|
|
[nas-install.md](nas-install.md) §9,
|
|
[ks2/nas-seed.md](../ks2/nas-seed.md).

## Instances
|
|
|
|
| Name | IP | Doc | Features |
|
|
|---|---|---|---|
|
|
| blocky | 192.168.0.254 | — | unprivileged, autostart; DNS ad-blocker for the LAN. Moved from nuc 2026-08-30 so it survives nuc being powered off |
|
|
| privoxy | 192.168.0.11 | — | unprivileged, autostart; filtering HTTP proxy, listens on **:3128** (not privoxy's default 8118); static config in `/etc/systemd/network/eth0.network`, `DNS=192.168.0.254`. Moved from nuc 2026-08-30 |
|
|
| [transmission-bt](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); `/export/media` disk device (`shift=true`), downloads to `/media/downloads`; web UI :9091 (LAN only). Moved from nuc 2026-08-30 |

## Backup pools hosted here
|
|
|
|
| incus pool | dataset | receives |
|
|
|---|---|---|
|
|
| `nucbackup` | `tank/backup/nuc` | nuc's instances (pushed nightly, 03:30) |
|
|
| `ks4backup` | `tank/backup/ks4` | ks4's instances (pulled over WG, 05:00 — after FTTH) |
|
|
| `nasbackup` | `tank/backup/nas` | **nas's own** instances (local copy, 04:00) |
|
|
|
|
nas's own instances are replicated **locally** rather than to nuc: nuc is
|
|
an on-demand box and usually powered off, so it is not a usable backup
|
|
target. `nasbackup` lives on `tank`, a different pool from the `incus`
|
|
SSD mirror the instances run on.
