February 27, 20233 yr after having issues i had to re set up my unraid server. I went click happy and added my cache drive (the one it use to be) to a disk spot on the array, i tried to stop array and change disk from array to cache but couldn't start the array. Should i just let it re build parity then change the disk to array then? Wish i wasn't gun hoe click happy but after a major issue i was just hoping to start it back up. I''l add diagnostic after parity sync is done but. can't i change it before hand....? i tried like i said and t wouldn't let me stat array to parity sync thanks for the help anything i can do or provide just let me know. i know i usually ad the diagnostic but i don't wanna stop it and have to stat at zero again..

February 27, 20233 yr Community Expert If it was added as a new device to an existing parity protected array it will be cleared (wiped) first, you can do a new config without it then re-assign as cache but any data there will be gone.

Attach Diagnostics to your NEXT post in this thread Seen to have been able to move the cache drive back to the pool and stat array, know its saying disk1 need to be formated and i dont want to loss the data on disk. should i wait for partiy sync or go ahead and format..? thanks in advance tower-diagnostics-20230227-0632.zip

February 27, 20233 yr Community Expert Comparing the 2 diagnostics you posted, it looks like you swapped parity2 and disk1 when you were reassigning disks. So you are now rebuilding parity2 over the former disk1 data, and the former parity2 is now waiting to be formatted as an empty disk1. Do you have backups of anything important and irreplaceable?
February 27, 20233 yr Community Expert Also looks like disk1 was unmountable in those first diagnostics, so my guess is you already made that same mistake earlier, assigning a data disk to a parity slot. Maybe you knew you had already done it wrong, and tried to fix it when you reassigned the 2nd time. Too late to save disk1 data.

February 27, 20233 yr Author just double checking and making sure i explain all details first to make sure i understand. when i go to look at my files, ISO,music, etc it only shows that it is being stored on disk 2-8, so i am just wondering if there is a way to double check if there even is anything on that disk before i hit format? not sure if i cant see disk one when i look at where my files are stored because it is unmounted currently or if its because my stuff isn't on there in general. is there a way to check? also even now, and my disk array says i still have 47% available space, but if it wasn't mounted right how would it know how much space i have available , and would it be the same as it was before? because it is the same as far as it looks. please let me know your thoughts and thanks for your patience reading through my thought process!
February 28, 20233 yr Community Expert If you format the disk, it will be empty and you can use it again for storing files. No way to know what might have been on it before.
February 28, 20233 yr Author can i mount it change the filesystem without formatting or is that my only option?
February 28, 20233 yr Community Expert You can't "mount" a disk that doesn't have a mountable filesystem. Whatever you set the filesystem to, the drive won't be mountable until you format it. Then it will have an empty filesystem of whatever type you chose. When you assigned that disk to a parity slot, whatever was on the disk before was overwritten by parity. Parity is just a bunch of bits, it has no filesystem and has none of your data. https://wiki.unraid.net/Manual/Overview#Parity-Protected_Array
