Filesystem/ko

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.

리눅스에는 여러가지 파일 시스템이 있으며 각 파일 시스템의 활용을 고려했을 때 장점과 단점이 있습니다.

디스크 파일 시스템

 * 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.

가상 파일 시스템

 * 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.

네트워크 파일 시스템

 * 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.

FUSE 기반 파일 시스템

 * 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.

마운트
파일 시스템은 여러가지 방식으로 마운트할 수 있습니다:


 * - 직접 파일 시스템을 마운트할 때 활용하는 명령어입니다. 관리 권한을 갖추거나 에 항목을 넣으면 됩니다.
 * fstab - 시스템에서 마운트할 수 있는 파일 시스템을 자세하게 알려주는 정보가 들어있습니다.
 * Removable media - 파일을 요청할 때마다 마운트합니다.
 * Udevil - 적은 의존성을 지닌 소규모 자동 마운트 유틸리티.
 * AutoFS - 파일에 접근할 때 자동으로 마운트합니다.

추가 참조

 * bcache - 리눅스 커널 블록 계층 캐시.
 * FUSE - 사용자 영역 파일 시스템(FUSE).
