I have two licensed Unraid servers tied to the same email address.  I think I have a bad USB drive in server1 - it is from 2017.  I am trying to replace my key but I am worried that I will blacklist server2, which is good, rather than server1. 

 

How does it work when you have multiple servers and you are trying to replace a key.  Does it give you an option on which one to replace, and were does that happen?

licenses are tied to guid of the usb key, not the email.

The email you recieved contains the GUID of the usb drive in the title you bought it on. So if you cannot recover the key directly from the failed flashdrive or the backups of that flashdrive, that would be the way to determin which one to replace.

Now, if you have purchased keys outside the unraid webgui, this might be a tat more tricky.

Thanks for the response, but my understanding is that when you click on Replace Key in the Unraid GUI it asks for you to enter your email address.  So does it know that this license is for usb drive with a GUID of, for example ABC123, and you are using a different drive at the current time.  And it won't try to send you a replacement for your other license that was for a USB drive, say with GUID XYZ789?  Therefore it knows that the replacement is for that particular drive, as opposed to any other licenses that you may have that are tied to that email account.

It asks for the email so it can send you the replacement key that way. It does know which GUID it had before as you can see below.


Ending with "50" was the new USB Drive, ending in "92" was where the key was before


Edit: I should mention, that you do need to have that particular key, for that particular old GUID.

Before you do any kind of replacement, Unraid should display the GUID the key thinks it has anyway. So in that case, you can check against your server2, if its that one or not.

Awesome, thanks.  For now I have avoided having to directly deal with this issue as when I restored the backup to my original USB drive all was well.  But this is the original USB key from 2017 on this server - or at least I am pretty sure that it is the original.  So it may not last too much longer and the issue that I had where it wouldn't boot may reoccur.

If your key is old, it may not be added to unraid connect yet, so try doing that, it will display the last 4 numbers so if you write those down somewhere with what USB it belongs to, when it fails you won't have any issues figuring it out.

If you don't want to use unraid connect, the GUID is visible in tools->registration as well, and when you click flash in your drive list.
