Today I tried to open up my Unraid dashboard and noticed I was getting a 502 error, so I ssh'd into the server. Nginx was complaining about a cert, and when I tried to look at the cert I got an Input/output error. Looking at it closer I notice my /boot folder appears empty. So, I guess I need to replace the USB stick. I can still ssh into the machine. I do have a backup of the contents of my config folder that's done frequently. I have not shut it down yet. Can I use the USB creator to make a new USB stick, copy my config folder over, and boot off it? I know I'll need to replace the license key.

Thanks. I only seem to have a backup of /boot/config and not all of /boot. Is that okay?

Yes. The rest should be the bz files for the OS unless you created some custom folders.

 

You should probably insert the old flash into another machine and run chkdsk first to see if you can repair it.

Thanks for your help. I'll try running chkdsk on it when I go get the replacement USB sticks tomorrow. Not shutting it down until then haha.

I would try first a different USB port, ideally USB2

Thanks. The USB stick was toast. Couldn't get any of my other computers to recognize it. I put the new one in, copied my configuration over, told it to replace the key, and... put in the email address I serve from the unraid box that is currently down, realizing that the second after I clicked send.

 

Can I put yet another USB stick into the machine and transfer again to my email address not served on the unraid box?

Probably not. LimeTech has a one a year limit on replacements last time I checked. You may want to email LT directly.

Ugh. What a stupid mistake on my part, and I was thinking before I did it that I would need to use my other email address. A friend serves as a relay (and I for him), but he's not where he can access it either. Perfect timing. I need it back up and running today if at all possible, so I guess I'll purchase a key using another USB stick, too. Been wanting to make a second, smaller box , so I guess I'll be buying that key early. When I get the other key in I can use that, too.

 

Again, thanks for all your help here.

LT is usually pretty quick to respond to emails, but it is a holiday weekend in the US so who knows.
