I have two quick questions that I couldn't find answered in the wikis, thought maybe a senior member could share a minute and clarify this for me.

 

First off, I have a Kingston DataTraveler in my server with the GUID of 0951-1603-0000-0000000000AF. Now I need to buy a license but it says the last twelve didgets should not be zeros. There is an "AF" on the end of mine so it's not "all" zeros, but it doesn't look like much of a serial number to me. Is this ok?

 

Secondly, where does unRAID store it's system data? If this flash drive dies, how would I get the server back up? If I put a new flash drive in wouldn't it be missing all the data on my array? Would I have to tell it which drive is which again? I was under the impression that no unRAID data was on the HDDs so it must be on the USB drive. Should I be backing it up?

 

Thanks

I don't know the answer to your first question, but I can answer your other questions:

 

Yes, unRAID stores it's non-user data on the flash drive.  If the flash drive dies, you will need another flash drive with unRAID installed to bring your server back online.  This second flash drive does not have to be identical to the first.  If this happens, you can email LimeTech, explain the situation, and they (he) will re-issue your unRAID license reflecting the new flash drive GUID.

 

Yes, you should definitely back up your flash drive on a regular basis, or at least every time you make a change to your system.  If you don't have a backup to work with and you have to start from scratch, all you will have to do is to tell unRAID which drives belong in which slots, paying extra attention to the parity drive.  The simple way to do this is to have a screenshot of the 'devices' page from before the first flash drive died.  This means that you should also be taking screenshots of your devices page every time you rearrange, add, or subtract any disks and have them backed up in a safe place apart from the unRAID server.  The crucial one to get right is the parity drive, as long as you get that one right the rest of the data disks don't really matter.  You can put them in any slot and unRAID will figure it out.  In addition to this reassignment of disks, you may also have to re-enter any particular configurations you have set up on your user shares.  unRAID will automatically detect your previous user shares (based on the folder structure across your data disks) and create the replacement user shares accordingly (without affecting your data), but you may have to repopulate the extra configuration fields such as 'included disks' and 'excluded disks'.

 

The bottom line is that if your flash drive fails your data will still be safe.

I figured it probably worked like that. Thanks for the information.

 

I guess I will just buy a pro license with this GUID and see if it works or not. Worst comes to worst I buy a new flash drive. I'll post back the results.

Send an email off to Tom at limetech and ask.  He is pretty quick about answering emails and it would avoid having to go through the headache of getting the license switched.

I already ordered a key with the above GUID. I figure if it isn't right then the transaction won't go through. In such an event I'll just have to dig up another drive.

Transaction went through and the Plus key is up and running.
