Great, thanks for the help!

Hi there. I upgraded today to 7.3, and upon reboot it showed 2 Read Errors on SSD cache Device 2. Diagnostics attached, and a SMART report of that drive. I guess I'm just looking for opinions on how serious this is? Thanks for any help or recommendations. tower-diagnostics-20260513-1736.zip

UPDATE: I was able to solve the problem. I used the unRAID USB Creator app on macOS to create a new USB stick using the zipped backup from my old stick, as per these instuctions: Changing the flash device | Unraid DocsThe USB flash device is critical to your Unraid server as it stores the operating system, configuration files, and license. If this device fails or becomes unreliable, prompt replacement is essential I shutdown my unRAID server, swapped the failed USB stick with this new one and booted it up. I set the password, then confirmed the drive assignments were still correct and started the array. Seems back to normal now.

Hello. This morning I'm seeing this error on my second unRAID server: "Missing key file. Your license key file is corrupted or missing. The key file should be located in the /config directory on your USB Flash boot device. If you do not have a backup copy of your license key file you may attempt to recover your key. If this was an expired Trial installation, you may purchase a license key." I was organizing some cables behind the computer, so it is possible that I bumped the unRAID USB stick. I can create a new one if needed. The Dashboard tab is blank when I click on it. And I clicked on the Apps tab and got this error: Fatal Boot Device Error This usually means your Boot Device is corrupted or has dropped offline. The rest of the Unraid GUI will also be affected. Post a new thread in the Unraid forums if this error continues. I was able to download a Flash backup from unRAID Connect dated yesterday. What are the next steps? Thanks. Diagnostics attached. tower2-diagnostics-20250914-0626.zip

Step 3 worked for me, using Google Chrome browser, thanks! I had made a fresh unRAID USB stick for a new server and couldn't register it in the Connect plugin for the life of me. Up and running now.

It’ll be ten years this November. Originally got it to store my media library, with some redundancy. Now I’ve added lots of Docker apps and scripts. I only wish I had more free time to spend on it!

That worked perfect, thanks!

Stupid question time: I'm not seeing that path anywhere...could you be more specific? 🤓 /opt/freefilesync/Resources/ Is that supposed to be in appdata? I only see a "Logs" folder in mine. Thanks.

Easy upgrade from 6.12.14 to 7 this weekend. Only a single issue, my ActualServer docker refused to start afterwards, but there are some suggested fixes on GitHub, which worked without too much hassle. Now learning about Tailscale (thanks for all the tutorial videos) and will explore the VM improvements at some point. Many thanks to all who make unRAID happen!

Welcome Nick!

Thanks for this template! Usually these apps require a separate database docker etc, so it's nice having this all setup automatically.

Thanks for this. A few of my docker containers were failing with the same error as in the first post. Turns out I had several orphaned docker images. I've deleted those, and did "Force Update" on each docker app that still wouldn't start, and now they're up and running again.

Thanks for the reply, will do.

Hello. Noticed this morning that I couldn't mount any unRAID shares. Had a look at the unRAID screen and turns out it had a kernel panic. Diagnostics are attached. I'm just wondering if something obvious (and bad?) had happened? I had to do a hard shutdown and restart, now it's running a parity check (which is a drag because I just did one on Thursday, plus it's gonna be 30 Celsius today, but oh well). Thanks for your time. tower-diagnostics-20230814-0807.zip
