To use RAID you must first create at least two partitions of type 'software RAID'. Then you can create a RAID device which can be formatted and mounted.
I ddefnyddio RAID rhaid i chi greu o leiaf dau raniad o'r math 'RAID meddalweddol' yn gyntaf. Wedyn gallwch greu dyfais RAID y gellir ei fformadu a'i gosod.
