This time I followed all directions and have successfully utillzed the usb flash creator and restored my server. I apologize for my misunderstandings and thank you both for your time, consideration and expertise. Thank you, again.

Sorry, i was listening to grok 3 about the bzroot. thebrainz-diagnostics-20250503-1202.zip

Hi @JorgeB, @itimpi, and community, Thank you, @JorgeB, for suggesting the USB Flash Creator and the download links at https://docs.unraid.net/unraid-os/download_list/ (posted 2 hours ago). I’ve tried both, but I’m still getting broken files, and my server can’t save diagnostic files. I’m sorry if my last post was confusing—let me explain. I have been trying to use USB Flash Creator. I have downloaded files for the manual method of installing unraid as well. However upon download, the bzroot files as described in section 1 below, are corrupted **What’s Happening**: 1. **Broken Files (bzroot)**: - I used the USB Flash Creator (7.0.1) on one PC to make boot USBs with my 32GB SanDisk USB and a 16GB Onn flash drive. Both gave a bad `bzroot` file (~33MB, should be ~300-400MB). - I also downloaded the 7.0.1 ZIP and 7.0.0 ZIP from unraid.net on multiple PCs. These either failed (403 Forbidden) or gave the same bad `bzroot` (~32-33MB). - The bad `bzroot` stops my server from starting properly (error: “Can’t find a SQUASHFS superblock”), so I can’t access the web interface, array, or Docker.

**Subject**: [UPDATE May 3, 2025] TheBrainz (7.0.1) - Diagnostics Not Saving, Invalid bzroot (~33MB), USB Flash Creator Used on 32GB SanDisk Hi @JorgeB, @itimpi, and community, Thank you, @JorgeB, for your continued support and request for new diagnostics (May 3, 2025). I’m unable to provide the latest diagnostics due to a saving issue, and I’ve clarified my USB Flash Creator attempts below. I need help with the diagnostics write failure and corrupted `bzroot`. **Diagnostics Saving Issue**: - Running `diagnostics` (May 2, 2025) shows `tower-diagnostics-20250502-1622.zip` (137K) in console (`ls -lh /boot/logs/tower-diagnostics-*.zip`), but after powering down, the file isn’t on USB (`E:\logs`, `dir E:\logs\tower-diagnostics-20250502-1622.zip` returns “path does not exist”). - Older diagnostics (`20250430-0449.zip`, `20250430-0806.zip`, 108 bytes) are invalid (per @itimpi, Apr 30). - Cause: Invalid `bzroot` (~33MB) creates a minimal Unraid environment without `emhttpd`, generating diagnostics in RAM but failing to write to `/boot` (`/dev/sda1`, vfat). `/boot` mounts correctly (`/dev/sda1 on /boot type vfat`), and `fsck.vfat -r` fixed the dirty bit (Apr 29), but writes fail. - Workaround: Provided `manual-diags-20250430-1414.txt` (Apr 30) with `lsblk -f`, memory, network, etc., as automated diagnostics don’t save. - Please confirm if `thebrainz-diagnostics-20250428-0001.zip` (169.64KB, Apr 28) or `manual-diags-20250430-1414.txt` can be used, or suggest how to force diagnostics to save. **Current State**: - **super.dat**: Restored to `/boot/config` (4096 bytes, Apr 29), matches assignments (Parity: sdf/2SGGBMKW, Disk1: sdd/VAGGS9UL, Disk2: sdb/1EHP4K4Z, Disk3: sde/VDKRMDYK, Disk4: sdc/JEKH3MZZ). Backed up to PC desktop. - **Plus.key**: On `/boot/config` (256 bytes, Nov 26, 2020). Backed up to PC desktop. - **Boot USB** (`/dev/sda1`, UNRAID, 2732-64F5): Invalid `bzroot` (33MB, Feb 25, 2025). - **32GB SanDisk USB**: Used with USB Flash Creator (7.0.1), produced 33MB `bzroot`. Will reuse if needed. - **ONN 16GB USB** (`/dev/sdg1`, 94A6-6C69 or `E:`, 15FF-052D): Not yet used with USB Flash Creator, will try on another PC with hotspot. - **Server**: Powered down, USB (`E:`) on PC. **Clarified Attempts**: - **USB Flash Creator**: Used on one PC (7.0.1) for `/dev/sda1` (2732-64F5) and 32GB SanDisk USB. Result: 33MB `bzroot`, fails to mount (“Can’t find a SQUASHFS superblock”). - **ZIP Downloads**: `unRAIDServer-7.0.1-x86_64.zip` (720,818,758 bytes, MD5: 81d1a615be90006422501597c7e30c19) downloaded on multiple PCs, gave 33MB `bzroot` or 403 Forbidden. `unRAIDServer-7.0.0-x86_64.zip` (May 2) gave 32MB `bzroot`. - **Secondary USB** (`/dev/sdg1`, WD My Passport, 09FB-203F): Used for transfers, misreports as 1.8TB (should be 32GB). - **Issues**: Corrupted `bzroot` blocks `emhttpd`, array, WebGUI, Docker. Diagnostics not saving. **Next Steps**: - Backed up `/config` (`super.dat`, `Plus.key`) to PC desktop. - Will try USB Flash Creator with ONN 16GB USB (94A6-6C69/15FF-052D) on another PC using hotspot. - Contacting Unraid support with Plus.key GUID for a verified 7.0.1/7.0.0 ZIP, as Unraid’s S3 bucket seems corrupted. **Questions**: - Why aren’t diagnostics saving to `/boot/logs`, despite `/boot` being mounted? - Can `thebrainz-diagnostics-20250428-0001.zip` or `manual-diags-20250430-1414.txt` suffice? - Is Unraid’s S3 bucket serving corrupted ZIPs? - Any mirror links for valid 7.0.1/7.0.0 ZIPs? - Tips for USB Flash Creator with ONN 16GB USB on new PC with hotspot? I’ll update after trying USB Flash Creator and hearing from support. Any tips, mirror links, or fixes for diagnostics saving? Thanks, Makaveli

**Reply to itimpi and JorgeB, Apr 30, 2025** Hi itimpi and JorgeB, thank you for your guidance! I’ve streamlined this post for clarity. **Response to itimpi (bz* Files and Diagnostics)**: - **emhttpd**: `/boot/bzroot` (33MB, Feb 25 17:25) and `bzroot` from `unRAIDServer-7.0.1-x86_64.zip` are invalid (“Can’t find a SQUASHFS superblock”). Redownloading Unraid 7.0.1 .zip from https://unraid.net/download to overwrite `bz*` files (`bzimage`, `bzroot`, `bzmodules`, `bzfirmware`) on `/boot`, as suggested.

**Update Apr 30, 2025** JorgeB, thank you for your continued guidance! I’ve restored `super.dat`, fixed the boot USB, SSH, and nginx (80/443), but I’m stuck restoring `emhttpd` due to invalid `bzroot` files, preventing array and WebGUI startup. **Actions Taken**: 1. **Initial Issue (Apr 24, 2025)**: - Bad `dd` and service commands corrupted `/boot/config/super.dat` (sbNumDisks=2, should be 5). - Array failed (`ERROR:NO_DEVICES`, `mdcmd: write error`), WebGUI down (HTTP 500), Docker stopped. - Boot USB (`/dev/sda1`) had dirty bit, SSH initially down. 2. **Diagnostics**: - `thebrainz-diagnostics-20250427-*.zip`, `tower-diagnostics-20250428-0944.zip`, `tower-diagnostics-20250429-2158.zip`. - New: `tower-diagnostics-20250430-0449.zip` (attached). 3. **super.dat Restoration (Apr 29, 2025)**: - Restored from `thebrainz-v7.0.0-flash-backup-20250314-0427.zip` (1.15GB, super.dat: Mar 6, 2025) to `/boot/config`. - Fixed boot USB: `fsck.vfat -r /dev/sda1` (resolved boot sector, dirty bit). - Unmounted `/boot` (`umount -l /boot`, no `lsof` output), copied via secondary USB (`/dev/sdg1`), rebooted. - Post-reboot: `super.dat` present (`ls -l /boot/config/super.dat`, 4096 bytes, Apr 29 12:42), but array not started, WebGUI down. 4. **SSH/Nginx**: - Restored SSH (PuTTY). - Nginx on 80/443: 5. **emhttpd Restoration Attempts**: - **Flash Backup**: `thebrainz-v7.0.0-flash-backup-20250314-0427.zip` lacks `emhttpd`. - **unRAIDServer-7.0.1-x86_64.zip**: - Downloaded (720,818,758 bytes, MD5: 81d1a615be90006422501597c7e30c19) to `C:\Users\Makaveli\Downloads`, copied to `/mnt/usb3` (`/dev/sdh1`, WD My Passport). - Fixed `/dev/sdh1` (previously `/dev/sdg1` failed): `fsck.vfat -r`, mounted at `/mnt/usb3`. - Verified .zip (`unzip -t`). Extracted `bzroot` (`unzip`, `unzip -p`): 33,222,768 bytes (~33MB, expected ~350MB). - Mount failed: “Can’t find a SQUASHFS superblock”.

Thank you, JorgeB, for your guidance. **Restoration Update**: Restored `super.dat` to `/boot/config` from `thebrainz-v7.0.0-flash-backup-20250314-0427.zip` (1.15 GB, `super.dat` dated March 6, 2025). Encountered "target is busy" with `umount /boot`, `lsof /boot` showed no output, confirmed shell was in `/root` via `pwd`, used `umount -l /boot` to unmount. Fixed USB dirty bit with `fsck.vfat -r /dev/sda1` (resolved boot sector difference by copying original to backup, removed dirty bit), copied `super.dat` using a secondary USB (`/dev/sdg1`), and rebooted. Post-reboot status: webGUI down, array not started. Reverted nginx to default ports (80/443), now restoring `emhttpd` from backup. Post-recovery status: [e.g., "webGUI up, array started"]. **Current State**: - `/boot/config/super.dat` is restored (see `ls -l /boot/config` below). - SSH is working via PuTTY. - nginx is on ports 80/443 (see `netstat` below). - Diagnostics: `/boot/logs/tower-diagnostics-20250428-0944.zip` (from previous post). **Console Outputs**: `ls -l /boot/config`: total 912 -rw------- 1 root root 1276 Oct 20 2020 DISK_ASSIGNMENTS.txt -rw------- 1 root root 256 Nov 26 2020 Plus.key -rw------- 1 root root 256 Sep 25 2020 Trial.key drwx------ 5 root root 16384 Apr 27 21:44 backups/ drwx------ 2 root root 16384 Feb 18 13:14 default/ -rw------- 1 root root 457 Apr 27 13:24 disk.cfg -rw------- 1 root root 2365 Apr 26 13:54 disk.cfg.bak -rw------- 1 root root 412 Apr 25 20:30 docker.cfg -rw------- 1 root root 302 Mar 23 10:14 domain.cfg -rw------- 1 root root 10 Apr 28 00:02 drift -rw------- 1 root root 40 Nov 25 07:38 editor.cfg -rw------- 1 root root 56 Feb 15 07:25 favorites.cfg -rw------- 1 root root 119 Feb 28 2022 flash.cfg -rw------- 1 root root 0 Apr 25 15:27 forcesync -rw------- 1 root root 412 Apr 23 05:45 go -rw------- 1 root root 551 Apr 23 05:13 go.bak -rw------- 1 root root 71 Jan 9 04:11 go~ -rw------- 1 root root 718 Apr 27 13:24 ident.cfg -rw------- 1 root root 33 Sep 24 2020 machine-id drwx------ 2 root root 16384 Apr 5 2021 modprobe.d/ -rw------- 1 root root 54 Nov 1 23:27 network-extra.cfg -rw------- 1 root root 373 Apr 25 22:15 network.cfg -rw------- 1 root root 327 Apr 23 03:29 network.cfg.backup -rw------- 1 root root 327 Apr 23 05:11 network.cfg.bak -rw------- 1 root root 353 Apr 25 22:07 network.cfg.bak22 -rw------- 1 root root 5089 Apr 1 17:57 parity-checks.log -rw------- 1 root root 628 Apr 27 12:21 passwd drwx------ 2 root root 16384 Mar 29 03:21 plugins/ drwx------ 2 root root 16384 Jan 25 13:10 plugins-error/ drwx------ 2 root root 16384 Mar 7 10:34 plugins-removed/ drwx------ 2 root root 16384 Apr 27 13:24 pools/ -rw------- 1 root root 32 Apr 28 00:02 random-seed -rw------- 1 root root 267 Feb 1 05:40 rsyslog.cfg -rw------- 1 root root 3792 Feb 1 05:40 rsyslog.conf -rw------- 1 root root 16384 Jan 9 04:11 secrets.tdb -rw------- 1 root root 472 Apr 27 12:21 shadow -rw------- 1 root root 527 Mar 2 10:51 share.cfg drwx------ 2 root root 16384 Apr 26 05:00 shares/ -rw------- 1 root root 26 Nov 6 07:17 smb-extra.conf -rw------- 1 root root 101 Apr 27 12:21 smbpasswd drwx------ 3 root root 16384 Apr 5 2021 ssh/ drwx------ 3 root root 16384 Sep 24 2020 ssl/ -rw------- 1 root root 4096 Apr 29 12:42 super.dat -rw------- 1 root root 4096 Apr 26 22:39 super.dat.bak -rw------- 1 root root 4096 Apr 27 12:13 super.dat.bak-20250427-121309 -rw------- 1 root root 4096 Apr 27 14:49 super.dat.bak-20250427-144926 -rw------- 1 root root 4096 Apr 27 22:22 super.dat.bak-20250427-222214 -rw------- 1 root root 4096 Apr 27 22:39 super.dat.bak-20250427-223942 -rw------- 1 root root 4096 Apr 27 22:53 super.dat.bak-20250427-230139 -rw------- 1 root root 4096 Apr 27 04:33 super.dat.bak2 -rw------- 1 root root 4096 Apr 27 22:00 super.dat.bak-manual-20250427-220035 -rw------- 1 root root 4096 Apr 27 12:22 super.dat.bak2-20250427-122259 -rw------- 1 root root 4096 Apr 27 09:19 super.dat.bak3 -rw------- 1 root root 4096 Mar 16 04:26 super.old -rw------- 1 root root 50 Mar 23 01:23 vfio-pci.cfg -rw------- 1 root root 918 Apr 27 21:47 super_backup_complete.tar.gz -rw------- 1 root root 50 Mar 23 01:23 vfio-pci.cfg.bak drwx------ 2 root root 16384 Apr 28 08:38 wireguard/ `netstat -tuln | grep -E ':(80|443|8080)'`: tcp 0 0 100.85.228.99:443 0.0.0.0:* LISTEN tcp 0 0 100.85.228.99:80 0.0.0.0:* LISTEN tcp 0 0 192.168.1.41:443 0.0.0.0:* LISTEN tcp 0 0 192.168.1.41:80 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:443 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:80 0.0.0.0:* LISTEN tcp6 0 0 ::1:443 :::* LISTEN tcp6 0 0 fd7a:115c:a1e0::5401:80 :::* LISTEN tcp6 0 0 fd7a:115c:a1e0::540:443 :::* LISTEN tcp6 0 0 ::1:80 :::* LISTEN **Questions**: - Did `super.dat` restore correctly?

Thank you, JorgeB, for your support. **Flash Backup**: Located the March 14, 2025, backup: `thebrainz-v7.0.0-flash-backup-20250314-0427.zip` (1.15 GB) at `C:\Users\Makaveli\Downloads`. Verified contents with `Expand-Archive` and `dir C:\Users\Makaveli\Downloads\temp\config` (output below). Confirmed `config/super.dat` exists (4096 bytes, dated March 6, 2025). Please provide console commands to restore `/boot/config/super.dat`, considering USB dirty bit and the `super.dat` date (March 6, 2025) vs. my server failure (April 24, 2025). **Disk Assignments**: Pre-April 24 GUI screenshot (attached previously) shows: - Parity: sdf (2SGGBMKW) - Disk1: sdd (VAGGS9UL) - Disk2: sdg (2SGGBMKW, duplicate serial, likely sdb: 1EHP4K4Z) - Disk3: sde (VDKRMDYK) - Disk4: sdc (JEKH3MZZ, synopsis lists sdc as 1EHP4K4Z, sdb as JEKH3MZZ) Current `lsblk -f` (console, Apr 28, 2025): - sdb: JEKH3MZZ (GUI Disk4) - sdc: 1EHP4K4Z (likely GUI Disk2, listed as sdb) - sdd: VAGGS9UL (Disk1) - sde: VDKRMDYK (Disk3) - sdf: 2SGGBMKW (Parity) - No sdg (GUI typo, should be sdb) Corrected assignments: - Parity: sdf (2SGGBMKW) - Disk1: sdd (VAGGS9UL) - Disk2: sdb (1EHP4K4Z) - Disk3: sde (VDKRMDYK) - Disk4: sdc (JEKH3MZZ) Can you confirm using diagnostics (`thebrainz-diagnostics-20250428-0001.zip`) or serials? If backup fails, how to reassign drives? **Current State**: - `/boot/config/super.dat` missing (`ls -l /boot`, Apr 28, 2025). - `/boot` mounted: `/dev/sda1 on /boot type vfat`. - USB: `fsck.vfat -n` shows dirty bit, boot sector differences. - SSH down; console access only. Running `systemctl status sshd`, `ip addr show eth0` (outputs pending). - New diagnostics: `/boot/logs/tower-diagnostics-20250428-0944.zip`. **Questions**: - How to restore `super.dat` from `thebrainz-v7.0.0-flash-backup-20250314-0427.zip`? - Should I fix USB dirty bit first (`fsck.vfat -r`)? - How to reassign drives if backup is invalid? - How to restore SSH? - Any risks to data (no writes, SMART PASSED)?
