The partition needs to be formated as a raid device, you should backup the data and create the raid array, then restore the data.
There may be other ways to do it, not sure.
If you have enough space for the raid partition already free then create the partition and move the data to it.
During install if you want to do it that way is the option for filesystem type
choose raid, then after creating enough partitions for the array you can create the array
