Hi

 

I just updated my OS but, when i rebooted, all the disks are now unassigned and I have no idea which one is the parity drive.

I know i should have labelled the drives in the case but hoping someone can advise me on how i can establish this after the fact?

 

Thanks in advance

Do you have a backup of your flash drive?

I did an update, but i have a backup of the previous version

Have you replaced any drives since the backup was taken?

Hi

 

No, I just updated the OS on the flash drive. Not been inside the case at all.

Thanks for replying Trurl. Diagnostics attached,

Those diagnostics show you assigning disks as parity, parity2, and disk1. But it doesn't look like you ever started the array so maybe OK. There is also an SSD which I assume you intend for cache. Are those the only disks you had?

 

If you have a flash backup why didn't you try to use it? Or at least ask about using it?

Please don't mess around with this. If you assign a data disk to a parity slot it will be overwritten with parity.

Also, those diagnostics seem to indicate no configuration, only defaults. But with no indication of any flash drive problems, and a Plus key already installed. As if you were starting from scratch with only your license.

How exactly did you do this update?

Hi Trurl

 

Thanks for looking at the diagnostics. I think that pretty much sums up my approach. I dont have the knowledge or skills to set this up so its pretty much default. I previously had a Drobo and, in truth, thats my level and i should probably have just replaced that with a newer version.

I could really do with a step by step 'idiots' guides for non-techies on how to optimise UNRAID but everything I've seen assumes understanding or prior knowledge that I just don't have.

TBH, I wasnt even aware that i had two drives allocated as parity, which seems like overkill for me as i currently only have four disks, and one of them is cache.

I guess I can deal with all this later but, for now, just need to know how to asign these disks without overwriting my data. There are files I need to access urgently.

As for updating my OS, all i did was run the USB creator and point it at the latest stable version. So that has just overwritten the original OS on the USB stick. Do you recommend I wipe the new OS and replace it with the backup from my previous version?

 

Thanks again for helping

Not sure whether the diagnostics show this but these are my disks.

Does this give any indication of where each should be asigned?  I was wondering about the (sdb,c,d,e etc.) suffix.

You can use this process from the online documentation that can be accessed via the Manual link at the bottom of the Unraid GUI.

So what you did was a fresh install instead of updating from the webUI. Therefore, you had none of your configuration.

 

All of your configuration is in the config folder on flash. If you replace that with the config folder from your backup you should get your configuration back.

Thanks Trurl, thats all it needed.

Thanks also to the other mods for your contributions.
