[MASOCH-L] Problema com RAID1 utilizando mdadm

Quando eu monto o raid manual com o comando: " mdadm -C -v /dev/md0 -l 1 
-n 2 /dev/hdc1 /dev/sda1" , ele funciona normalmente. Mas quando eu faço 
pelo arquivo de configuração ele não funciona.
Aqui vai o arquivo de configuração:

vim /etc/mdadm/mdadm.conf

DEVICE partitions
DEVICE /dev/sda1,/dev/hdc1
ARRAY /dev/md0 devices=/dev/sda1,/dev/hdc1
#ARRAY /dev/md0 level=1 devices=/dev/sda1,/dev/hdc1

# auto-create devices with Debian standard permissions
#CREATE owner=root group=disk mode=0660 auto=yes

# automatically tag new arrays as belonging to the local system
#HOMEHOST <system>

# instruct the monitoring daemon where to send mail alerts
#MAILADDR root



E o erro que aparece:
