# xfsprogs-4.19.0

## 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-8.4 platform.

## Kernel Configuration

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

    File systems --->
      <*/M> XFS filesystem support [CONFIG_XFS_FS]

## 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 PKG_DOC_DIR=/usr/share/doc/xfsprogs-4.19.0 install     &&
    make PKG_DOC_DIR=/usr/share/doc/xfsprogs-4.19.0 install-dev &&

    rm -rfv /usr/lib/libhandle.a                                &&
    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@" /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.
xfs_spaceman | reports and controls free space usage in 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.
