GNU Parted is a package for creating, destroying, resizing, checking, and copying partitions and the file systems on them. This is useful for creating space for new operating systems, reorganizing disk usage, copying data between hard disks, and disk imaging. It contains a library, libparted, and a command-line frontend, parted, which also serves as a sample implementation and script backend.
AVFS (A Virtual File System) is an easy-to-install system that enables all programs to access archived, compressed, remote, or other kind of virtual files without the need to recompile programs or the kernel. The following modules are currently implemented: tar, zip, rar, gzip, bzip2, ftp, http, dav, rsh/ssh, floppy, and many more.
FSlint is a toolkit to find various forms of lint on a filesystem. At the moment it reports duplicate files, bad symbolic links, troublesome file names, empty directories, non stripped executables, temporary files, duplicate/conflicting (binary) names, and unused ext2 directory blocks.
The dump package contains both dump and restore. Dump examines files in a filesystem, determines which ones need to be backed up, and copies those files to a specified disk, tape or other storage medium. The restore command performs the inverse function of dump; it can restore a full backup of a filesystem. Subsequent incremental backups can then be layered on top of the full backup. Single files and directory subtrees may also be restored from full or partial backups.
Bonnie++ is based on the Bonnie hard drive benchmark by Tim Bray. The most notable features that have been added are support for >2G of storage and testing operations involving thousands of files in a directory. This program is used by ReiserFS developers, but can be useful for anyone who wants to know how fast their hard drive or file system is. It now includes ZCAV in the package. This program tests the performance of different zones on the hard drive. ZCAV has been released separately before but will now only be released as part of the Bonnie++ suite.
CDfs is a file system for Linux systems that `exports' all tracks and boot images on a CD as normal files. These files can then be mounted (e.g. for ISO and boot images), copied, played (audio tracks), etc. The primary goal for developing this file system was to `unlock' information in old ISO sessions. The file system also allows you to access data on faulty multi session disks, e.g. disks with multiple single sessions instead of a multi session.
autofs is a kernel-based automounter for Linux. It performs a job similar to amd but relies on a small stub of kernel code instead of pretending to be an NFS server. The result is simpler code, better reliability, and much faster operation in the common case (everything already mounted). Autofs 4 adds support for automounting trees of exported filesystems via /net.
