====== Making new RAID5 ======

Tell the system that my disks will be raided:

Correct autoraid:

<code>
/sbin/fdisk /dev/sdd1
p
t
fd
w
</code>

do this for each disk:

<code>
/sbin/mdadm --create --verbose --raid-devices=3 --level=5 /dev/md0 /dev/sdd1 /dev/sde1 /dev/sdf1
/sbin/mdadm --detail --scan > /etc/mdadm.conf
</code>

# Check
<code>
/sbin/mdadm --detail  /dev/md0
</code>

<code>
/sbin/mkfs.ext3 /dev/md0
mount /dev/md0 /dataxrd
</code>

Correct fstab:
<code>
/dev/md0                /dataxrd                   ext3    defaults        0 0
</code>

===== Resemble RAID5 =====

Make RAID5 from existing disks (which were in RAID5 before)

<code>
/sbin/mdadm -A  /dev/md0 /dev/sdd1 /dev/sde1 /dev/sdf1
/sbin/mdadm --detail --scan > /etc/mdadm.conf
</code>
