Hello, I've been noticing more and more that my server seems generally unstable. My intuition tells me its related to my USB as its a USB 3.0 and as time has gone on I can't go more than a few days without things cropping up and having to restart. Most recently in no particular order, these issues have come up and going away after a restart.

Unraid GUI being unreachable (this seemed like a plugin problem)

Unraid GUI not serving me all the tabs. they are reachable but just blank. Followed by these errors in my syslog.

Server nginx: 2023/11/25 19:22:46 [crit] 3437#3437: *375050 pread() "/usr/local/emhttp/webGui/styles/default-white.css" failed (5: Input/output error) while sending response to client, client: 10.0.0.70, server: , request: "GET /webGui/styles/default-white.css?v=1692979133 HTTP/1.1", host: "192.168.0.69", referrer: "http://192.168.0.69/Dashboard"

Alot of messages that look like the following in my syslog

Server kernel: SQUASHFS error: xz decompression failed, data probably corrupt
Server kernel: SQUASHFS error: Failed to read block 0x10079bf0: -5
Server kernel: SQUASHFS error: Unable to read fragment cache entry [10079bf0]
Server kernel: SQUASHFS error: Unable to read page, block 10079bf0, size 829c

 

Dockers being completely unresponsive and the full context menu not appearing when trying to open webGUIs on them.

SMB just straight up crashing

 

Maybe im on the right track with the USB? I have a 2.0 USB on order to eliminate that possibility. Ive checked the USB for any errors on windows and nothing stands out.

 

Any help or thoughts is appreciated!

These messages do suggest a flash drive problem.

Okay thanks, my understanding is that most of the OS is loaded into RAM on boot up. Is there still files that get accessed throughout the time that the system is booted?

Yes, some firmware files use the flash drive

As a bit of an update, switched to a 2.0 USB and haven't experienced anywhere near the problems I was encountering before. We will see as time goes on, but very stable right now.

 

Switching USBs was an involved process though, I think incase anyone finds this later. Some things that need to be done in order to switch your boot USB, that aren't documented well.

 

After writing the flash backup onto the new USB make sure you:
1. Delete all the old *.key files:

I had my Trial.key and Basic.key on my usb previously in /config. With them there, the "replace USB key" was not available.

2. Install Unraid Connect

When pressing the replace button, it wouldn't finish the transfer after logging into the popup window. It only properly functioned once I had installed the connect app.

You should keep the .key file you are replacing. That is how it knows you have a paid version. That file will be replaced when your license is transferred to the new flash drive.

right, I should have been more clear, my USB contained the Trial, Basic, and Plus keys. I had to remove the Trial and Basic but kept my Plus key as that is my current one. Then the button to transfer to a new USB appeared in Tools > Registration. Whereas before removing the keys it was not an available option.
