Добрый день. Давно был собран raid1 из двух дисков, и после отключения и подключения дисков он перестал работать. Ниже состояние системы. Хотелось был либо как-то восстановить raid1 или разобрать но что бы сохранились все данные. Боюсь сам что-то делать т.к. не уверент что мои действия не похерят все данные.
