{{Warning box|Get it right or you will lose data. '''Take a backup!''' Keep in mind if you make a mistake you can loose a whole hard disk. A common error is to switch /dev/sda with /dev/sdb.}}
SME Servers Raid Options are largely automated, if you built your system with a single hard disk simply logon as ''admin'' and select ''Disk Redundancy'' to add a new drive to your RAID1 array. The same procedure is used if you have a disk failure in a RAID array and you have replaced that failed disk.
But with the best laid plans things don't always go according to plan, these are the processes required to do it manually.

{{Warning box|as the dd command is named "data destroyer" you need to be extremely prudent and sure of the name of source partition and/or destination. At first you should skip the dd command, Step 1 below, and attempt to install grub without it, see Step 2 below. If grub can be installed without using dd, then Step 1 can be discarded. }}
