Partitions are initially set up during the installation process. DiskDrake allows you, to some extent, to resize your partitions, move them, etc. DiskDrake can also deal with RAID devices and supports LVM but we will not discuss these advanced uses here.
DiskDrake is very powerful and can therefore be a dangerous tool. Misuse could very easily lead to data loss on your hard drive. Because of this potential loss of data, you are strongly advised to take some protective measures before using DiskDrake:
DiskDrake enables you to manage partitions on each physical hard drive on your machine, and also on removable drives: USB hard disks, keys, memory cards, etc. You can see as many tabs as hard drives your system has. Each tab is named after the Linux name for that drive (for example: sda for the first hard disk).
The window (see Figure 7.1, “DiskDrake's Main Window”) is divided into four zones:
Bottom. Buttons for executing general actions. See Section 7.1.2, “DiskDrake's Action Buttons”.
We are now going to do a
little exercise to demonstrate one of the more useful features of
DiskDrake. Let us imagine that you decide to
use your machine as an FTP server and you want to
create a separate
/var/ftp partition in order to host
the FTP files. Note that doing this
step-by-step tutorial will actually modify the structure of your hard
The next step, as you may have
guessed, is to click on the button. A
dialog appears which allows you to choose the new size for the
/home partition. Move the slider to reflect the
new size, then click on .
When resizing is done,
the graphic representation of your hard drive changes. The
/home partition is smaller, and an empty space
appears. Click on the empty space and then on the
button. A dialog will let you choose the
parameters for the new partition. Set the size, choose the file system
you want to use (usually
Journalized FS: ext3) and
then enter the mount point for the partition, which in our example
The last step is to format (prepare to host files) the
newly created partition. To format the partition, click on its
representation in the partitions picture, then on the
button. Confirm the writing of the
partition table to disk, the formatting of the partition and the
update to the
/etc/fstab file. You may be asked
to reboot the computer to make changes effective.
