Previously I had setup a ubuntu server using mdadm with 4x 2TB drives. One of my drives died and since this was my backups of my data on different servers I didn't care about losing it.
Since then, I've purchased a replacement drive and some new server hardware. I completely reinstalled ubuntu on my SSD, then I deleted the partition table and volumes on all 4 of the 2TB drives. Then I went to create a brand new array but when I do, it immediately says degraded and it is trying to resync my new drive with the old array I had setup.
How do I just get it to create a new array so I can format the entire array and create a new empty volume?
Note: I was doing this in the Ubuntu desktop in the unity GUI with the disk utility.
Since then I've changed over to a full headless server install, but I still want to create this array so it doesn't try to resync the replacement disk.
