9.14.2. Adding Partitions

To add a new partition, select the Create button. A dialog box appears (refer to Figure 9.41, “Creating a New Partition”).

Note

You must dedicate at least one partition for this installation, and optionally more. For more information, refer to Appendix A, An Introduction to Disk Partitions.

9.14.2.1. File System Types

Fedora allows you to create different partition types and file systems. The following is a brief description of the different partition types and file systems available, and how they can be used.
Partition types
  • standard partition — A standard partition can contain a file system or swap space, or it can provide a container for software RAID or an LVM physical volume.
  • swap — Swap partitions are used to support virtual memory. In other words, data is written to a swap partition when there is not enough RAM to store the data your system is processing. Refer to the Fedora Deployment Guide for additional information.
  • software RAID — Creating two or more software RAID partitions allows you to create a RAID device. For more information regarding RAID, refer to the chapter RAID (Redundant Array of Independent Disks) in the Fedora Deployment Guide.
  • physical volume (LVM) — Creating one or more physical volume (LVM) partitions allows you to create an LVM logical volume. LVM can improve performance when using physical disks. For more information regarding LVM, refer to the Fedora Deployment Guide.
File systems
  • ext4 — The ext4 file system is based on the ext3 file system and features a number of improvements. These include support for larger file systems and larger files, faster and more efficient allocation of disk space, no limit on the number of subdirectories within a directory, faster file system checking, and more robust journaling. The ext4 file system is selected by default and is highly recommended.
  • ext3 — The ext3 file system is based on the ext2 file system and has one main advantage — journaling. Using a journaling file system reduces time spent recovering a file system after a crash as there is no need to fsck [3] the file system.
  • ext2 — An ext2 file system supports standard Unix file types (regular files, directories, symbolic links, etc). It provides the ability to assign long file names, up to 255 characters.
  • xfs — XFS is a highly scalable, high-performance file system that supports filesystems up to 16 exabytes (approximately 16 million terabytes), files up to 8 exabytes (approximately 8 million terabytes) and directory structures containing tens of millions of entries. XFS supports metadata journaling, which facilitates quicker crash recovery. The XFS file system can also be defragmented and resized while mounted and active.
  • vfat — The VFAT file system is a Linux file system that is compatible with Microsoft Windows long filenames on the FAT file system.

Note

The Btrfs file system is unavailable in Fedora 17.


[3] The fsck application is used to check the file system for metadata consistency and optionally repair one or more Linux file systems.
