November 9, 20241 yr Hi All, I'm new to Unraid so the thinking/logic below may be uninformed, and hopefully what I've written makes sense! I have 1x 16TB parity drive and 1x 16TB array drive which does not need encryption. I also have 2x 4TB drives that I would like to combine into a 8TB array and encrypt that array. So I'd end up with 16TB non encrypted array and a 8TB encrypted array. The reason I ask is because I far as I understand, you cannot encrypt individual shares, only disks. And so rather than encrypting each 4TB as separate drives, ideally I want to combine them into a 8TB array and then encrypt the array. If it's not possible to create a second array (and encrypt it) with the 2x 4TB drives, what's the best way to implement such a setup using just one array? (and is it even possible?) Lastly, would the parity drive be able to work with the encrypted array? Many Thanks

Set those 2 drives as encrypted as part of the array and set up the share you want encrypted to only use those 2 disks.
November 9, 20241 yr Author Ah ok cool - simple as that! I was obviously overthinking it 3 hours ago, Dominoes0522 said: Lastly, would the parity drive be able to work with the encrypted array? I assume the encrypted drives will be backed up by the parity drive in the same way that any non-encrypted drive would be? Thanks
November 9, 20241 yr Community Expert Parity has no idea at all of what is on the drives, only that bit X should be Y in case the drive vanished and needed to be emulated/rebuilt. Encryption or not doesn't matter. It is not a backup. Edited November 9, 20241 yr by Kilrah
