# Lone Star Electrical — Unraid Server USB Replacement & Re-registration (2026-06-02)

## Session Summary

The Lone Star Electrical Unraid server was failing to boot, halting at `bzfirmware checksum error - press ENTER key to reboot...`. The boot console showed Unraid verifying its boot files against stored SHA256 sums; `bzimage`, `bzroot`, `bzroot-gui`, and `bzmodules` all passed, but `bzfirmware` failed its checksum, so the OS never mounted and the box looped on reboot. The flash drive (label UNRAID, `/dev/sda1`, Generic 8GB) was detected and `fsck.fat` ran clean (758 files, no FAT errors), isolating the fault to the corrupt `bzfirmware` file content rather than the filesystem.

This was first triaged earlier in the day on another machine. The initial fix — replacing the corrupt `bzfirmware` file on the existing USB — did not hold: after rebooting, the same checksum error recurred. The recurrence confirmed the original diagnosis that the 8GB generic USB flash drive itself was failing (the #1 wear item on Unraid), not a one-off file corruption.

Howard migrated the server to a new USB flash drive. He used the official **Unraid USB Creator** to write **Unraid 7.1.4** to the new stick (which handles FAT32 format, the `UNRAID` volume label, the `bz*` OS files, and installing the syslinux bootloader / boot flag in one step). He then copied the **`config/` folder from the old flash drive** onto the new stick to preserve the array configuration (`super.dat` disk assignments, shares, network settings, and the existing license `.key`).

Because a new USB has a new GUID, the existing license key would not validate against it. Howard completed the license **re-registration / key transfer** to bind the license to the new flash GUID. The server is now booting off the new stick. Mike is having a Claude session run a check on the server to verify health/array state. This log is being saved so a Syncro ticket can be created and notes updated.

## Key Decisions

- Replaced the entire USB flash drive rather than re-replacing the `bzfirmware` file again — the recurrence after a file-level fix confirmed the stick was failing, so a fresh stick was the correct remediation.
- Used the Unraid USB Creator (vs. manual file copy + `make_bootable`) to guarantee a properly bootable stick with correct label/bootloader.
- Preserved the old `config/` folder verbatim on the new stick to retain disk assignments and avoid reconfiguring the array; only the OS files were fresh (from 7.1.4).
- Completed the license key transfer to the new GUID rather than running indefinitely in Trial mode.

## Problems Encountered

- **Recurring `bzfirmware` checksum error on boot.** Initial fix (replacing the `bzfirmware` file on the old USB) failed — error returned after reboot. Root cause: failing USB flash drive. Resolved by migrating to a new USB stick written with the Unraid USB Creator (7.1.4) + copied `config/`.
- **New USB = new GUID, old license invalid.** The copied `.key` would not validate against the new flash GUID. Resolved by completing the Unraid license key transfer/re-registration to the new stick.

## Configuration Changes

- New Unraid boot USB flash drive created for the Lone Star Unraid server (Unraid **7.1.4** via USB Creator).
- Old `config/` folder (super.dat / shares / network / `.key`) copied from the failing stick onto the new stick.
- Unraid license re-registered / transferred to the new flash GUID.

## Credentials & Secrets

- **No Lone Star Unraid credential is vaulted.** Vault search returned only ACG's own Unraid boxes: `infrastructure/jupiter-unraid-primary.sops.yaml` (Jupiter, 172.16.3.20) and `infrastructure/uranus-unraid.sops.yaml` (Uranus, 172.16.3.21) — neither is the Lonestar server.
- Unraid login is always user `root`; the root password is stored in `config/shadow` on the flash, so the original Lonestar root password carried over with the copied `config/` folder.
- **TODO:** capture the Lonestar Unraid root password and create a vault entry for this server (hostname, IP, Unraid 7.1.4, license type). Not yet vaulted.

## Infrastructure & Servers

- **Lone Star Electrical Unraid server** — exact hostname / LAN IP / license type not yet documented (verify and add to vault + wiki).
- Boot device (failed): label UNRAID, `/dev/sda1`, Generic Flash Disk 8GB (8.05 GB / 7.50 GiB).
- Now running: Unraid **7.1.4** on a new USB flash drive.
- Client: Lone Star Electrical Systems LLC — Syncro customer ID `33809612`. Google Workspace shop (`lonestarelectrical.net`), ManageEngine MDM. Primary contact: Robin Eneix (robine@lonestarelectrical.net).

## Commands & Outputs

- Boot failure (verbatim from console): `Verifying bzfirmware checksum ...` → `bzfirmware checksum error - press ENTER key to reboot...`; preceding `umount: /: not mounted`.
- `fsck.fat 4.2 (2021-01-31)`: `/dev/sda1: 758 files, 231850/1961984 clusters` (clean — filesystem healthy, file content corrupt).

## Pending / Incomplete Tasks

- **Create Syncro ticket** for Lone Star Electrical documenting the Unraid USB failure + replacement + re-registration (this is the explicit reason for saving).
- **Mike's Claude session is running a health check on the server** — capture results (array start state, disk assignments, parity validity, registration status) and fold into the ticket/notes.
- **Verify array integrity before/after start:** confirm all disks landed in correct slots from the copied `super.dat`; ensure no unwanted parity rebuild was triggered.
- **Vault the Lonestar Unraid credentials** (root password) and **document the server in the wiki** (hostname, IP, Unraid 7.1.4, license type).
- Keep the old failing USB stick as a temporary backup until the new stick is confirmed stable; then retire it.

## Reference Information

- Unraid downloads / USB Creator: https://unraid.net
- License transfer/registration: webGUI → Tools → Registration → Replace Key (self-service transfer limited to once per 12 months; LimeTech support for dead-stick reissue).
- Files on a bootable Unraid stick: `bzimage`, `bzroot`, `bzroot-gui`, `bzmodules`, `bzfirmware` (+ matching `.sha256`), `syslinux/`, `make_bootable*`. The `config/` folder holds array/license state and must be preserved across migrations.
- Lonestar wiki: `wiki/clients/lonestar-electrical.md`. Syncro customer: `33809612`.

## Update: 22:10 PT — LS-1 Sophos removal prep + packetdial sync resurrection

### Session Summary
Resumed the long-pending Sophos Endpoint removal on the Lone Star workstations (the `SophosED.sys` kernel boot driver that blocks every user-mode removal; offline WinRE/PE completion was staged 2026-05-29). Howard has both LS-1 and LS-2 on hand plus a bootable PE. Pulled the exact offline procedure from the 2026-05-29 sophos-removal log and walked it through for LS-1.

Started with LS-1. Howard booted into normal Windows to verify BitLocker before the offline edit (PE cannot reach `System32` on a locked volume without the recovery key). Confirmed BitLocker is OFF on LS-1, and staged `SophosZap.exe` in Downloads for the post-reboot cleanup. LS-1 was about to boot to PE to run the driver delete + offline-hive service disable. Awaiting the `dir` drive-letter check from PE before greenlighting the `del`.

Separately, a `/sync` exposed a fleet repo-coordination problem: the `.claude/skills/packetdial/` skill was sitting untracked on HOWARD-HOME, so `git add -A` re-committed it just as Mike's incoming commit `c759f04` ("re-apply consolidation deletions") deleted it. The rebase replayed the add on top of the delete, resurrecting packetdial at HEAD (`dd414c4`) and pushing it back to origin — the exact additive-sync resurrection loop Mike's commit message was fighting (memory files deleted in `0c00010` were resurrected by `sync-memory.sh` on GURU-5070). Flagged to Howard; packetdial is a live, functional skill in the registry, so its deletion inside a memory-consolidation commit may have been collateral. Left the keep/re-delete decision to Mike rather than acting unilaterally.

### Key Decisions
- Verified BitLocker OFF on LS-1 from inside Windows before the PE step, rather than discovering a locked volume at the PE prompt — avoids needing the recovery key mid-procedure.
- Did NOT unilaterally re-delete the resurrected packetdial skill nor silently keep it; surfaced to the human (Mike's call) because it is a working skill and its deletion may have been unintentional collateral in a memory-cleanup commit.
- Deferred the broadcast `/self-check` fleet-census request (from GURU-5070) until after the LS-1 field work, rather than interrupting the active ticket.

### Problems Encountered
- **Push race during sync.** First `sync.sh` push rejected ("fetch first") because the remote advanced between fetch and push. Resolved by re-running sync (fetch + rebase + push succeeded: `c759f04..dd414c4`).
- **packetdial skill resurrection.** Untracked local files re-added by additive sync, undoing Mike's deletion. Surfaced for Mike's decision; not yet resolved.

### Configuration Changes
- `.claude/skills/packetdial/` (SKILL.md, references/api.md, scripts/ns.py, scripts/ns_client.py) re-added to repo at `dd414c4` (UNINTENTIONAL resurrection — pending Mike's keep/delete decision).
- Pulled in from fleet: `.claude/skills/self-check/` + `.claude/commands/self-check.md` (Mike), guru-connect/gururmm submodule bumps, memory consolidation deletions.

### Infrastructure & Servers
- **LS-1, LS-2** — Win11 workstations, Lone Star Norris site. BitLocker confirmed OFF on LS-1. Sophos removal blocked by `SophosED.sys` kernel boot driver (`Start=0`).
- Service to disable in offline hive: `Sophos Endpoint Defense` (set `Start=4`).

### Commands & Outputs
- Offline removal (run in PE, substitute real Windows drive letter for `D:`):
  - `del /f D:\Windows\System32\drivers\SophosED.sys`
  - `reg load HKLM\TEMPSYS D:\Windows\System32\config\SYSTEM`
  - `reg add "HKLM\TEMPSYS\CurrentControlSet\services\Sophos Endpoint Defense" /v Start /t REG_DWORD /d 4 /f`
  - `reg unload HKLM\TEMPSYS`
  - reboot normal, then `SophosZap.exe --confirm`
- Drive-letter discovery in PE: `dir C:\Windows & dir D:\Windows & dir E:\Windows`
- BitLocker check (normal Windows, elevated): `manage-bde -status`

### Pending / Incomplete Tasks
- **LS-1:** boot PE, confirm Windows drive letter, run offline SophosED.sys removal, reboot, `SophosZap --confirm`. Awaiting drive-letter check.
- **LS-2:** same offline procedure, not yet started.
- **Syncro ticket** "Sophos Endpoint Removal - LS-1 and LS-2": verify it exists / create, then log time (prepaid block, live-check `GET /customers/33809612`).
- **packetdial resurrection:** Mike to decide keep vs. re-delete; offered to send a coord message to him.
- **Fleet `/self-check`:** run on HOWARD-HOME after field work, apply fixes, re-run to GREEN, then `/self-check --publish`.
- Vault + document the Lonestar Unraid server (root pw, hostname, IP, license type).

### Reference Information
- Coord handoff: msg `689cfb7c` (2026-06-01, Sophos removal to Howard).
- Mike's deletion commit: `c759f04` "chore(memory): re-apply consolidation deletions + lift additive-only constraint".
- HEAD after sync: `dd414c4`.
- Full LS-1/LS-2 offline procedure: `clients/lonestar-electrical/session-logs/2026-05-29-sophos-removal.md`.

## Update: 17:39 PT — Sophos removal COMPLETE (LS-1 + LS-2) + Unraid ticket

### Session Summary

Completed the long-pending Sophos Endpoint removal on both Lone Star Norris workstations (LS-1 and LS-2), then created/closed the Syncro ticket for the earlier Unraid boot-USB replacement. Both removal jobs were driven remotely through GuruRMM once each machine was back in Windows.

LS-1 was resumed from the offline-PE prep done earlier (driver renamed, BitLocker confirmed off). The blocker turned out to be more than the kernel driver: SophosZap refuses to run while the registry flag `HKLM\SYSTEM\CurrentControlSet\services\Sophos Endpoint Defense\TamperProtection\Config\SEDEnabled = 1`. Because the SophosED tamper driver was not loaded this boot (renamed offline), the flag could be cleared live as SYSTEM (`SEDEnabled=0`). SophosZap v1.9.158.0 then ran two passes (with a reboot between) via RMM and reported clean — no Sophos services, drivers, folders, or Add/Remove entries; Windows Defender real-time protection active.

LS-2 was done via the manual offline (WinRE) procedure since it was offline in RMM at the start. Howard loaded the offline SYSTEM hive and set the SED service `Start=4` + `SEDEnabled=0`, then renamed the Sophos driver files. On reboot the machine dropped into Automatic Repair. The `SrtTrail.txt` root cause was explicit: "Boot critical file C:\WINDOWS\system32\DRIVERS\SophosEL.sys is corrupt" — i.e. missing because it was renamed. `SophosEL.sys` is the **Sophos ELAM** (Early Launch Anti-Malware) driver: `Start=0` (Boot), `ErrorControl=3` (Critical), so its absence aborts boot. Recovery: booted back to PE and renamed `SophosEL.sys.old` back to `SophosEL.sys`; the machine then booted.

Once LS-2 was back in Windows, an RMM read of the service config showed the earlier offline edits had actually landed correctly: `Select\Current = 0x1` (ControlSet001 IS active), the SED tamper driver service (`Sophos Endpoint Defense`, SophosED.sys) was already `Start=4`, and `SEDEnabled` was 0 — so tamper protection was already neutralized. SophosZap then ran two passes via RMM (with a verified-safe reboot between — `SophosEL.sys` confirmed present on disk and no pending Sophos file-renames before rebooting) and reported clean. Defender active on LS-2.

Billing: created/closed two Syncro tickets against the Lone Star prepaid block (customer 33809612). #32347 (Sophos removal LS-1+LS-2): 2.0h in-shop, invoiced $0.00, block 17.0 -> 15.0, Closed. #32372 (Unraid boot-USB replacement, documenting the earlier 2026-06-02 server fix): 1.5h in-shop, invoiced $0.00, block 15.0 -> 13.5, Closed.

### Key Decisions

- Cleared `SEDEnabled=0` (the SophosZap tamper gate) rather than only relying on the driver rename — the registry flag, not the driver presence, is what SophosZap checks.
- LS-2: after the boot failure, did NOT re-rename the boot-critical `SophosEL.sys`. Restored it and relied on the (already-correct) SED service `Start=4` + `SEDEnabled=0` to neutralize tamper, letting SophosZap remove the ELAM driver itself the boot-safe way.
- Verified `SophosEL.sys` present + no pending Sophos file-renames BEFORE the pass-2 reboot on LS-2, to avoid repeating the boot failure.
- Drove both machines via GuruRMM (read service config, set registry, run SophosZap, reboot) rather than hands-on once each was in Windows.

### Problems Encountered

- **LS-2 boot failure (Automatic Repair).** Root cause (SrtTrail.txt): boot-critical `SophosEL.sys` (Sophos ELAM, Start=0/ErrorControl=3) was renamed and thus "corrupt"/missing. Resolved by booting to PE and renaming `SophosEL.sys.old` back to `SophosEL.sys`.
- **SophosZap blocked by tamper flag, not driver.** First LS-1 run errored "SophosZap does not run with tamper protection on" with the driver already renamed — the `SEDEnabled=1` registry flag was the gate. Resolved by setting `SEDEnabled=0`.
- **Offline ControlSet correctness.** The offline edit used `ControlSet001`; this only worked because `Select\Current=0x1`. Documented that the active control set must be read from `HKLM\OFFSYS\Select\Current` before editing; `CurrentControlSet` does not exist in an offline hive.
- **PE PowerShell script closed on error.** The first-draft `Remove-Sophos-Offline-PE.ps1` exited (window closed) on an unhandled error. Hardened with a top-level try/catch + guaranteed `Read-Host` pause; abandoned in favor of the manual walkthrough for this job.

### Configuration Changes

- LS-1, LS-2: Sophos Endpoint Protection fully removed (services, drivers, `C:\Program Files\Sophos`, `C:\Program Files (x86)\Sophos`, `C:\ProgramData\Sophos`, Add/Remove entries, catalogs, certs). Windows Defender now the active AV on both.
- LS-2 registry (offline, ControlSet001): `Sophos Endpoint Defense` service `Start=4`; `...\TamperProtection\Config\SEDEnabled=0`, `IgnoreSAV=0`.
- Created `clients/lonestar-electrical/scripts/Remove-Sophos-Offline-PE.ps1` (offline PE removal helper; hardened error handling).

### Credentials & Secrets

- None created or changed. (Lone Star Unraid root password still not vaulted — pre-existing TODO.)

### Infrastructure & Servers

- **LS-1** GuruRMM agent id `6b9617fa-5c77-40e1-8b64-a1545e730895` (windows).
- **LS-2** GuruRMM agent id `97fe5582-aa3d-4132-94a6-f4c8582bca31` (windows).
- Sophos drivers (LS-2): `SophosED.sys` (2,561,552 B) = "Sophos Endpoint Defense" tamper driver, Type 2, ended at Start=4; `SophosEL.sys` (28,616 B) = "Sophos ELAM", Type 1, Start=0/ErrorControl=3 (BOOT-CRITICAL).
- SophosZap: v1.9.158.0; log at `C:\WINDOWS\SystemTemp\SophosZap log.txt`; staged to `C:\Windows\Temp\SophosZap.exe` for pass 2.

### Commands & Outputs

- Tamper gate (per SophosZap log): `Value 'SEDEnabled' ... is set to 1. Tamper-protected by SED. ERROR: SophosZap does not run with tamper protection on`.
- Clear it (live, SYSTEM): `reg add "HKLM\SYSTEM\CurrentControlSet\services\Sophos Endpoint Defense\TamperProtection\Config" /v SEDEnabled /t REG_DWORD /d 0 /f`.
- Offline (PE): `reg load HKLM\OFFSYS X:\Windows\System32\config\SYSTEM` -> edit under `HKLM\OFFSYS\ControlSet001\Services\...` -> `reg unload HKLM\OFFSYS`. Active set from `reg query HKLM\OFFSYS\Select /v Current`.
- LS-2 boot root cause: `Boot critical file C:\WINDOWS\system32\DRIVERS\SophosEL.sys is corrupt` (SrtTrail.txt). Fix: `ren X:\Windows\System32\drivers\SophosEL.sys.old SophosEL.sys`.
- Removal run: `SophosZap.exe --confirm` x2 (reboot between); final outcome `error flag: 0`, services/drivers/folders NONE, Defender RTP True.

### Pending / Incomplete Tasks

- Vault the Lone Star Unraid root password + document the server (hostname, IP, Unraid 7.1.4, license type) in the wiki — still open.
- Keep the old failing Unraid USB stick as backup until the new stick is confirmed stable, then retire.
- Optional: delete leftover `SophosEL.sys.old` on LS-2 if any remained (cleanup attempted in pass 2).

### Reference Information

- Syncro: #32347 (Sophos removal, id 111423954, invoice 1650552617) and #32372 (Unraid USB, id 112022651, invoice 1650552739) — both Closed, prepaid, customer 33809612. Block now 13.5 hrs.
- RMM API base `http://172.16.3.30:3001`.
- PE removal script: `clients/lonestar-electrical/scripts/Remove-Sophos-Offline-PE.ps1`.
- Offline procedure reference: `clients/lonestar-electrical/session-logs/2026-05-29-sophos-removal.md`.

### Update: 18:10 PT — open-item disposition

- **Old Unraid USB stick retired** — new stick confirmed registered and stable; old one pulled.
- **Remaining Unraid items handed to Mike** (coord todo `de75eec6`): set + vault the root password (`clients/lonestar-electrical/unraid-server.sops.yaml`), document hostname/IP/license type, verify array integrity, and investigate a **LimeTech/Unraid API skill** (Unraid 7.x GraphQL API via the `unraid-api`/Connect plugin) if those functions exist. Deferred until Mike posts a note on what he did with the machine — not to be chased before then.
- **LS-1 / LS-2 location:** both desktops are at the Computer Guru office for repair (confirmed via LS-2 being on the ACG `172.16.0.0/22` network — ARP showed 172.16.3.20/.21/.30). Returning onsite to Norris and reconnected the week of 2026-06-08.
- LAN discovery attempt: LS-2 had no SMB mounts / mapped drives to the Lonestar Unraid box, so its IP/hostname were not auto-discoverable; left for Mike's follow-up.
