Filesystem/fr

A filesystem is Article description::a means to organize data expected to be retained after a program terminates by providing procedures to store, retrieve, and update data as well as manage the available space on the device(s) which contain it.

Un système d'exploitation GNU/Linux peut utiliser divers systèmes de fichiers (voir ci-dessous).

Systèmes de fichiers usuels

 * bcachefs - A next generation, robust, high performance filesystem supporting CoW (Copy-on-write), compression, and encryption.
 * Cramfs - A memory and space sensitive compressed filesystem that supports random reading. It avoids the block device layer and tiny embedded systems with very tight memory constraints.
 * eCryptfs - The enterprise cryptographic filesystem for Linux.
 * efivarfs - a (U)EFI variable filesystem
 * ext4 - The default, GPL licensed journaling filesystem for many Linux distributions.
 * FAT - The File Allocation Table (FAT) filesystem. Originally created for use with Microsoft Windows.
 * JFS - A GPL licensed, 64-bit Journaled File System (JFS) developed by IBM.
 * Btrfs - A copy-on-write B-tree file system (Btrfs) with advanced features (an entirely open source licensed ZFS alternative).
 * NTFS - Microsoft Windows' New Technology File System (NTFS) (Windows' default filesystem).
 * Aufs - Advanced multi-layered unification file system (Aufs), formerly known as Another union file system.
 * OverlayFS - The only union-like filesystem built-in to the Linux kernel.
 * ReiserFS - Version 3 of the ReiserFS filesystem.
 * Reiser4 - Version 4 of ReiserFS filesystem. Currently not implemented in the mainline Linux kernel.
 * SquashFS - A compressed, read-only file system for Linux
 * UDF - Universal Disk Format - needed for mounting some kind of .iso files
 * GFS2 - Global File System 2: A shared disk filesystem. Typically used in compute clusters.
 * UFS - The Unix File System (UFS) also called the Berkeley Fast File System.
 * XFS - A GPL licensed, 64-bit journaling filesystem created by Silicon Graphics.
 * ZFS - A CDDL (non-GPL compatible) licensed, copy-on-write filesystem created by Sun Microsystems.
 * F2FS - A Flash-Friendly File System (F2FS) created by Samsung for the Linux kernel.

Systèmes de fichiers virtuels

 * debugfs - Used for debugging purposes; primarily Linux kernel development.
 * procfs - Used to output and change of system and process information.
 * securityfs - Used by the TPM BIOS character driver and IMA, an integrity provider.
 * sysfs - Used to output information about and to configure devices and drivers.
 * tmpfs - Used to store files in memory (RAM).
 * devtmpfs - requires devtmpfs (Maintain a devtmpfs filesystem to mount at ) in the kernel.

Systèmes de fichiers distribués

 * Ceph - A distributed object store and filesystem designed to provide excellent performance, reliability, and scalability.
 * NFS - A common Linux network file system protocol.
 * SSHFS - Implements FUSE to mount filesystems in user space.
 * Tahoe-LAFS - A Least Authority File Store (LAFS).
 * GlusterFS - A powerful network/cluster filesystem.

Systèmes de fichiers de type FUSE

 * CurlFtpFS - File system for accessing FTP hosts based on FUSE.
 * exFAT - A FUSE filesystem for the extended FAT filesystem.
 * FuseISO - FUSE module to mount ISO filesystem images.
 * MTPfs - A FUSE filesystem providing access to Media Transfer Protocol (MTP) devices.
 * smbnetfs - A FUSE filesystem for SMB shares.
 * squashfuse - Mount SquashFS archives using FUSE.

Montage
Les systèmes de fichiers peuvent être montés de plusieurs façons :


 * - Commande utilisée pour monter manuellement les systèmes de fichiers. Son utilisation requiert des privilèges d'administrateurs sauf si le système de fichiers est spécifié dans le fichier (voir ci-dessous).
 * fstab - Ce fichier indique comment monter les systèmes de fichiers qui y sont mentionnés.
 * Média amovible - Gestion automatique du montage.
 * Udevil - Petit utilitaire ayant peu de dépendances qui permet une gestion automatique du montage.
 * AutoFS - Montage automatique lors de l'accès à un fichier se situant sur le système de fichiers.
