Удалить mdadm raid1 без потери данных

У меня есть 2 hdd's в raid1 с помощью mdadm,

Теперь я хочу полностью отключить рейд, но хочу сохранить данные на диске 1 и использовать диск 2 отдельно

Есть ли способ сделать это.

Я буду честен, я знаю, что такое рейд, но я понятия не имею, как он обрабатывается mdadm,

Я использую Ubuntu 14.04

Конфигурация:

mdadm: /dev/md does not appear to be an md device
