Beyond Linux® From Scratch (systemd edition) - Version 7.6-systemd

Chapter 5. File Systems and Disk Management

xfsprogs-3.2.1

Introduction to xfsprogs

The xfsprogs package contains administration and debugging tools for the XFS file system.

This package is known to build and work properly using an LFS-7.6 systemd platform.

Package Information

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/xfs

Kernel Configuration

Enable the following options in the kernel configuration and recompile the kernel: 

File Systems:
  XFS filesystem support: M or Y

Installation of xfsprogs

Install xfsprogs by running the following commands: 

make DEBUG=-DNDEBUG INSTALL_USER=root INSTALL_GROUP=root \
     LOCAL_CONFIGURE_OPTIONS="--enable-readline"

This package does not come with a test suite.

Now, as the root user: 

make install install-dev &&
rm -rfv /lib/libhandle.{a,la,so} &&
ln -sfv ../../lib/libhandle.so.1 /usr/lib/libhandle.so &&
sed -i "s@libdir='/lib@libdir='/usr/lib@g" /usr/lib/libhandle.la

Command Explanations

make DEBUG=-DNDEBUG: Turns off debugging symbols.

INSTALL_USER=root INSTALL_GROUP=root: This sets the owner and group of the installed files.

LOCAL_CONFIGURE_OPTIONS="...": This passes extra configuration options to the configure script. The example --enable-readline parameter enables linking the XFS programs with the libreadline.so library, in order to allow editing interactive commands.

OPTIMIZER="...": Adding this parameter to the end of the make command overrides the default optimization settings.

Short Descriptions

fsck.xfs

simply exits with a zero status, since XFS partitions are checked at mount time.

mkfs.xfs

constructs an XFS file system.

xfs_admin

changes the parameters of an XFS file system.

xfs_bmap

prints block mapping for an XFS file.

xfs_copy

copies the contents of an XFS file system to one or more targets in parallel.

xfs_estimate

for each directory argument, estimates the space that directory would take if it were copied to an XFS filesystem (does not cross mount points).

xfs_db

is used to debug an XFS file system.

xfs_freeze

suspends access to an XFS file system.

xfs_fsr

applicable only to XFS filesystems, improves the organization of mounted filesystems, the reorganization algorithm operates on one file at a time, compacting or othewise improving the layout of the file extents (contiguous blocks of file data).

xfs_growfs

expands an XFS file system.

xfs_info

is equivalent to invoking xfs_growfs, but specifying that no change to the file system is to be made.

xfs_io

is a debugging tool like xfs_db, but is aimed at examining the regular file I/O path rather than the raw XFS volume itself.

xfs_logprint

prints the log of an XFS file system.

xfs_mdrestore

restores an XFS metadump image to a filesystem image.

xfs_metadump

copies XFS filesystem metadata to a file.

xfs_mkfile

creates an XFS file, padded with zeroes by default.

xfs_ncheck

generates pathnames from inode numbers for an XFS file system.

xfs_quota

is a utility for reporting and editing various aspects of filesystem quota.

xfs_repair

repairs corrupt or damaged XFS file systems.

xfs_rtcp

copies a file to the real-time partition on an XFS file system.

libhandle.so

contains XFS-specific functions that provide a way to perform certain filesystem operations without using a file descriptor to access filesystem objects.
