Čitanje stanja RAID polja:
mdadm --detail /dev/md0
Degradirano polje (ono koje je izgubilo jedan disk, ali i dalje radi) daje ovakav prikaz:

Dodavanje sdb3 particije u mda0 RAID polje (ako je polje degradirano, automatski regenerira polje s novim diskom/particijom, u suprotnom novu particiju/disk dodaje kao rezervni uređaj):
mdadm --add /dev/md0 /dev/sdb3
Da bi promjene ostale i nakon restarta potrebno je urediti i /etc/mdadm.conf datoteku - dodati disk/particiju u DEVICES liniju:
# mdadm.conf written out by anaconda MAILADDR root DEVICE /dev/sda3 /dev/sdb3 ARRAY /dev/md0 level=raid1 num-devices=2 UUID=xxxx
