e2fsprogs - Werkzeuge für ext2-/ext3-/ext4-Dateisysteme

Beschreibung

Die Dateisysteme ext2, ext3 und ext4 sind Nachfolger des ursprünglichen ext-Dateisystems (ext ist die Abkürzung von extended, erweitert). Diese Dateisysteme werden am häufigsten für Festplatten in Debian- und anderen Linux-Systemen verwendet.

Dieses Paket enthält Programme zum Erstellen, Überprüfen und Warten von ext2/3/4-Dateisystemen. Es enthält auch das Programm badblocks, mit dem nach schadhaften Blöcken auf einer Festplatte oder anderen Speichergeräten gesucht werden kann.

TMP

e2fsprogs (sometimes called the e2fs programs) is a set of utilities for maintaining the ext2, ext3 and ext4 file systems. Since those file systems are often the default for Linux distributions, it is commonly considered to be essential software.

Werkzeuge

Werkzeug	Beschreibung
badblocks	search a device for bad blocks
blkid	locate/print block device attributes
chattr	change file attributes on a Linux file system
debugfs	used to manually view or modify internal structures of the file system
dumpe2fs	prints superblock and block group information.
e2freefrag	report free space fragmentation information
e2fsck	an fsck program that checks for and corrects inconsistencies
e2image	save critical ext2/ext3/ext4 filesystem metadata to a file
e2label	change the label on an ext2/ext3/ext4 filesystem
e2scrub	check a filesystem "online" (i.e. without having to unmount it) in the case where the filesystem is on an LVM LV
e2undo	replay an undo log for an ext2/ext3/ext4 filesystem
e4defrag	online defragmenter for ext4 filesystems
filefrag	report file fragmentation
findfs	find a filesystem by label or UUID
findsuper	quick hacked up program to find ext2 superblocks
logsave	save the output of a command in a logfile
lsattr	list file attributes on a Linux second extended file system
mke2fs	used for creating ext2, ext3 and ext4 file systems
resize2fs	which can expand and shrink ext2, ext3 and ext4 file systems. On-line support was added in 2006.[2]
tune2fs	used to modify file system parameters

Many of these utilities are based on the libext2fs library.

Usage

Despite what its name might suggest, e2fsprogs works not only with ext2, but also with ext3 and ext4. Although ext3's journaling capability can reduce the need to use e2fsck, it is sometimes still necessary to help protect against kernel bugs or bad hardware.

As the userspace companion for the ext2, ext3, and ext4 drivers in the Linux kernel, the e2fsprogs are most commonly used with Linux. However, they have been ported to other systems, such as FreeBSD and Darwin.
