Поднял сервер на debian8, систему установил на отдельный диск. Два диска WD взял с synology. Там они находились в raid1. Хотелось бы не стирая с дисков информации снова включить диски в raid1. Подскажите как это сделать.
если сделать это невозможно, то хотя бы извлечь информацию с дисков.

если попробовать примонтировать md2 (из под root):
/dev/md2 /mnt/sdc ext3 user,auto,rw 0 0
bash: /dev/md2: Permission denied
sudo mount /dev/md2
mount: can't find /dev/md2 in /etc/fstab
sudo mount /dev/sdb5

cat /etc/fstab
