Unit summary: System configuration
Topic A In this topic, you learned that disk drives attach to either the IDE/ATA or SCSI bus on
your computer. Linux uses device files to represent the disk drive itself and the
partitions it contains. You used fdisk and mkfs to define partitions and create file
systems usable by Linux. You modified the fstab file to mount the volumes when you
boot your computer. You also mounted a virtual file system—an ISO file representing
the contents of a CD-ROM disc—and used the files it contained.
Topic B In this topic, you learned how to manage file systems. You determined how much disk
space was used and available with both command-line and GUI tools. You also learned
how to check ext-based file systems with the e2fsprogs command. And you learned
how to do the same for xfs-formatted disks with XFS related commands.
Topic C In this topic, you learned that disk quotas limit the amount of disk space users or
groups may use. You enabled quotas on a partition and set quota limits. You learned
about disk arrays and the various RAID levels. Finally, you examined logical volume
management and the benefits of LVM.
Topic D In this topic, you learned that files in the /dev directory represent the devices in your
system. You used some of the special devices, such as /dev/null and /dev/random. You
then viewed the devices on your computer’s USB and PCI buses.
1 In terms of hard drives, what is a cylinder?
A logical collection of all the tracks at a given distance from the axis.
2 What is the device name assigned to the second IDE/ATA hard drive on your
3 In Linux, a partition containing an ext2 or ext3 file system will have a partition type
ID of ________.
4 In Linux, a swap partition will typically have a partition type ID of ________.
5 True or false? The second partition on the first SCSI hard drive is /dev/hds2.
False. It is /dev/sda2
6 Linux requires a minimum of ________ partitions.
Two: the root and swap partitions
7 Which utility or utilities would you use to define new partitions on a hard drive?
8 True or false? GParted is available for Windows.
True, in the form of a bootable “live” CD.
