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.

List of utilities

Included with e2fsprogs, ordered by ASCIIbetical order, are:

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.
