This is from coonnect my unraid webpage - When I select management and login I get this:

From Connect I tried to create a USB revcovery but it fails when generating?

What to do next? All applications is running/dockers /shares etc.
Afraid to reboot?

Please advice, Thanks

Reboot to see if it comes back, it could be a bad flash drive, or it can just have dropped, if it comes back up with a reboot, try using a different USB port.

Ok SSH into server and after running:
dmesg | grep -i sda

I can see the USB is faulty:

[507936.087098] FAT-fs (sda1): Directory bread(block 30623) failed

[507936.087100] FAT-fs (sda1): Directory bread(block 30624) failed

[507936.087102] FAT-fs (sda1): Directory bread(block 30625) failed

[507936.087104] FAT-fs (sda1): Directory bread(block 30626) failed

......

The bacup Download works now (didnt last night) so I have a backup I can restore to a new USB.
I do use the recommended Samsung USB drives but I guess everything breaks over time :-)

This can also happen if the flash drive drops, so it may still be worth trying a different port.

Ok I made the backup USB but before that I just moved the existing USB to another port and it worked?
I have never in all my years of Unraid have this happen?
Should I replace the USB (Its not that old and on the recommended list) or just keep the existing one?
What do you recommend?

I would keep it for now, but if the same thing happens on the different port, then replace it.

Ok got the error again replaced the USB with a brand new same model as existing one the Samsung USB:

So created a new Unrad installation and copied all the config folder to the new stick, but it just hangs at:

So I tried the old USB again and it boots up.... (I know it will fail again soon)
Can anyone explain this? (I followed the recover guide, and also downloaded yesterdays Flash backup and restored the config folder)

Thanks all

Hi, I had the same issue and I think it was also the same model of USB key (exact model name is "Samsung Memory MUF-32BE3EU USB Key SAMSUNG 32G USB 3.1 BAR Plus" according to amazon).

It's a sturdy key but I think the metal part makes it overheat.

Sometimes it disappeared from the BIOS, sometimes it was detected but failed during unraid boot.

Each time I had to reboot, I had to change of USB port for the key to be accepted, it went for a couple of months. I initially thought of an issue with my motherboard.

Obviously after a while it just died when I was writing on it (during some changes of shares configuration) and crashed my server.

I replaced it with a SanDisk Cruzer Blade and now everything is ok.

I had also the same issue, what I did is made a zip backup of my old USB key and restored it on the new USB key with the unraid usb tool creator.

That look more like a flash drive issue, but you can try with a stock install, just to make sure it's not a config problem, which I doubt.

Thanks!

Okay finally got the prdered new USB sticks and I followed the transfer to new.
But after loggeing into Unraid connect and selecting to transfer I got the input link to key?
I ignored that because I did not receive any link to a new key? - Is that worng?
everything is running fine now the sandisk started without problem (Took alittle longer seems it had to try different resolution ( I have my server attached to a monitor)
But I guess its because its a first boot?

Still a bummer I have a pile of the Samsung sticks that I can use.
Anyone have alternatives to booting from a normal USB?

It was mentioned in the latest Uncast video that booting from different devices should be possible in the near future.
