Čitanje stanja RAID polja:
 mdadm --detail /dev/md0

Degradirano polje (ono koje je izgubilo jedan disk, ali i dalje radi) daje ovakav prikaz:
<pre>

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
