I have 3 drives in a Storage Space on Windows 8. I am running a two way mirror. The drives are 2x2TB and 1x1TB. I want to remove the 1TB drive without replacing it. In other words, I only want the 2x2TB drives. How do I do this / is this possible to remove a drive without putting a new drive in its place? There is no "remove button" in the GUI, and I am not familiar with Powershell commands.
As long as all your storage spaces have parity or mirroring just remove the drive. If you have any simple storage spaces you will want to copy that data to a new storage space with resiliency and then remove the drive. The storage space status should then show a missing driving and allow you to select remove link.
