the same amount of space as the smallest sized partition. The RAID partitions should be stored on
different hard disks to decrease the risk of losing data if one is defective (RAID 1 and 5) and to
optimize the performance of RAID 0. After creating all the partitions to use with RAID, click
RAID
> Create RAID to start the RAID configuration.
In the next dialog, choose among RAID levels 0, 1, and 5, then click Next . The following dialog (see
Figure 8-1 ) lists all partitions with either the Linux RAID or Linux native type. No swap or DOS

device (for example,
/dev/md0
) is shown in the list. Unassigned partitions are indicated with “--”.
