The E2fsprogs package contains the utilities for handling the ext2 file system. It also supports the ext3 journaling file system.
It is recommended that E2fsprogs be built in a subdirectory of the source tree:
mkdir -v build cd build
Prepare E2fsprogs for compilation:
../configure --prefix=/usr --with-root-prefix="" \ --enable-elf-shlibs --disable-evms
The meaning of the configure options:
Certain programs (such as the e2fsck program) are considered essential programs. When, for example, /usr is not mounted, these programs still need to be available. They belong in directories like /lib and /sbin. If this option is not passed to E2fsprogs' configure, the programs are installed into the /usr directory.
This creates the shared libraries which some programs in this package use.
This disables the building of the Enterprise Volume Management System (EVMS) plugin. This plugin is not up-to-date with the latest EVMS internal interfaces and EVMS is not installed as part of a base LFS system, so the plugin is not required. See the EVMS website at http://evms.sourceforge.net/ for more information regarding EVMS.
Compile the package:
To test the results, issue: make check.
One of the E2fsprogs tests will attempt to allocate 256 MB of memory. If you do not have significantly more RAM than this, it is recommended to enable sufficient swap space for the test. See Section 2.3, “Creating a File System on the Partition” and Section 2.4, “Mounting the New Partition” for details on creating and enabling swap space.
Install the binaries and documentation:
Install the shared libraries:
Searches a device (usually a disk partition) for bad blocks
A command line utility to locate and print block device attributes
Changes the attributes of files on an ext2 file system; it also changes ext3 file systems, the journaling version of ext2 file systems
An error table compiler; it converts a table of error-code names and messages into a C source file suitable for use with the com_err library
A file system debugger; it can be used to examine and change the state of an ext2 file system
Prints the super block and blocks group information for the file system present on a given device
Is used to check, and optionally repair ext2 file systems and ext3 file systems
Is used to save critical ext2 file system data to a file
Displays or changes the file system label on the ext2 file system present on a given device
Reports on how badly fragmented a particular file might be
Finds a file system by label or Universally Unique Identifier (UUID)
Is used to check, and optionally repair, file systems
By default checks ext2 file systems
By default checks ext3 file systems
Saves the output of a command in a log file
Lists the attributes of files on a second extended file system
Converts a table of command names and help messages into a C source file suitable for use with the libss subsystem library
Creates an ext2 or ext3 file system on the given device
By default creates ext2 file systems
By default creates ext3 file systems
Used to create a lost+found directory on an ext2 file system; it pre-allocates disk blocks to this directory to lighten the task of e2fsck
Can be used to enlarge or shrink an ext2 file system
Adjusts tunable file system parameters on an ext2 file system
Creates new UUIDs. Each new UUID can reasonably be considered unique among all UUIDs created, on the local system and on other systems, in the past and in the future
Contains routines for device identification and token extraction
The common error display routine
Used by dumpe2fs, chattr, and lsattr
Contains routines to enable user-level programs to manipulate an ext2 file system
Used by debugfs
Contains routines for generating unique identifiers for objects that may be accessible beyond the local system
