Feel like I'm missing something obvious here but I literally cannot figure it out. I'm on unRAID 7. I have a miniPC with a single SSD drive. It was an upgrade from 6.x and so that SSD is the "array" - Its the only drive.

 

I was given some instructions that in order to remove my SSD from the array I had to add another drive to the array and then use the unbalanced tool to move (scatter) the folders on the SSD (/appdata, /doman etc etc) to the new array drive then do some "tool/new config" option to then free the SSD from the array then use unbalanced to put the folders back onto the SSD once I mark it as a "pool/cache" drive.

 

Ignoring the fact that unbalanced shows me all sorts of warnings:

 

Owner70052

file(s)/folder(s) with an owner other than 'nobody'

Group70050

file(s)/folder(s) with a group other than 'users'

Folder permissions26174

folder(s) with a permission other than 'drwxrwxrwx'

File permissions70049

files(s) with a permission other than '-rw-rw-rw-' or '-r--r--r--'

You can find more details about which files have issues in the log file (/var/log/unbalanced.log).
At this point, you can transfer the folders/files if you want, but be advised that it can cause errors in the operation.
You are suggested to install the Fix Common Problems plugin, then run the Docker Safe New Permissions command.

 

No idea if I can even proceed with that step....

 

But more fundamentally....

 

I've added a spinning HDD to the array. As a test I thought I would remove it from the array. Absolutely cannot figure out HOW to do that. I would hace epxected a simple "remove from array" button. There isn't even any file or folders on the drive as it was just added. I've stopped the array and then moved that slot 2 to "no device" but then I cannot start the array as "a drive is missing"....  I've tried "tools/new config" but that seems scary as I don't want to lose anything so I kept "preseve all" ticked. But no way to remove drive like that as far as I can tell.

 

What am I missing? This should not be so elusive.

You don't need to do that, just do a new config, create a pool, and assign it there.

When you say that when I stop the now two disk (SSD + HDD) array and then select select "Tools, New Config" do I leave "preserve current assignments" as none and then go in to what are now two unassigned drives and assign the SSD to be a "new" pool/cache drive and the HDD to what will be a new array?

 

The wording of that sounds to me like I would lose all my dockers (/appdata etc on the SSD) and the drives would all become unassigned?

Just to be clear, in the end you just want the SSD assigned to a pool or also the HDD assigned to the array?

Really I just want the SSD to be out of the array (it was the only drive in the array on 6.x) so that it can now be the cache/pool drive (and contain the docker /appdata folder full time)...  I can then worry about adding disks to an array later on now that 7.x doesn't require an array at all.

 

So ideally - after I do this I just want the SSD to keep working as it is today for my docker images but not in an array so that TRIM etc works and it acts as the base pool/cache drive for the future as I do add drives to an array. The spinning HHD I did add to the array with the SSD prior I just want to go back into the "unasssigned drives" list for now....

 

Thanks so much for the guidance here!!

Just do a new config, don't keep any assignments, then back on main, add a new pool, assign the ssd , start the array.

Magic that worked. I was massively overthinking it. However feels like the language and guidance on how to do this could be much clearer in the online docs. I was super concerned the "tools, new config" would break stuff once I reassigned the drives to their new places...  However once I put the SSD into its new pool (cache) I was able to start array and all is good I just have the SSD and all my spinning HDD's are now unassigned. Exactly what I wanted. Thanks for the patience and helping on this dumb question!
