Hi. I have broken array with only parity drive active, data drive was dead, so I precleared 2 new 2TB HDD, one for parity and other for data, the question is how can I copy all my files from array (parity drive) without adding new drive to array or maybe I can unassign parity drive and then make new array and copy data from old parity which would be outside array but inside unraid (copy from one drive to another in unraid machine, no usb hdd or lan as a copy chain). Is it possible? I know that I can just add precleared drive in current array and it automatically resync from parity, then unassign parity drive and assign new hdd for parity slot. But I want to make new clean array and don't worry about problems that can be brought from old array.
