Hello,
until now I was only using Unraid with one single unassigned drive for testing. Now I wanted to upgrade my setup with 3 more drives of the very same type (same producer, same series, same capacity) so that 2 would be parity drives and one would become my initial encrypted data-drive. the contents of the one year "old" drive would then be copied to the array and then afterwards the drive would be added to the array later on.
I powered down clean and took out the "old" drive since I wanted to place it to another SATA port. One of the new drives (for parity) is now sitting where the old "drive" used to be.
When starting Unraid I cannot start the array. It says to the left side: "Stopped. Invalid expansion." and to the right side I see: "You may not add new disk(s) and also remove existing disk(s).".
The "old"disc has a green circle in front and the other three drives have blue squares.
Can anybody help me to proceed? How can I install the two drives as parity?
Greetings
