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.

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

User

• User: Howard Enos (howard)

• Role: tech

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.
