A place for files that might change frequently - especially in size, for example e-mail sent to users on the system, or process-ID lock files. /var/log: Contains system log files. /var/mail: The place where all incoming mail is stored. Users (other than root) can access their own mail only. Often, this directory is a symbolic link to /var/spool ...
The Unix file system (UFS) is a family of file systems supported by many Unix and Unix-like operating systems. It is a distant descendant of the original filesystem used by Version 7 Unix . Design
Modern Linux distributions include a /sys directory as a virtual filesystem (sysfs, comparable to /proc, which is a procfs), which stores and allows modification of the devices connected to the system, [20] whereas many traditional Unix-like operating systems use /sys as a symbolic link to the kernel source tree.
ext – Extended file system, designed for Linux systems. ext2 – Second extended file system, designed for Linux systems. ext3 – A journaled form of ext2. ext4 – A follow-up for ext3 and also a journaled filesystem with support for extents. ext3cow – A versioning file system form of ext3.
A log-structured filesystem is a file system in which data and metadata are written sequentially to a circular buffer, called a log.The design was first proposed in 1988 by John K. Ousterhout and Fred Douglis and first implemented in 1992 by Ousterhout and Mendel Rosenblum for the Unix-like Sprite distributed operating system.
The ext4 file system resides in a disk image, which is treated as a file (or multiple files, depending on the hypervisor and settings) in the NTFS host file system. Having multiple file systems on a single system has the additional benefit that in the event of a corruption of a single file system, the remaining file systems will frequently ...
XFS was ported to the Linux kernel in 2001; as of June 2014, XFS is supported by most Linux distributions; Red Hat Enterprise Linux uses it as its default file system. XFS excels in the execution of parallel input/output (I/O) operations due to its design, which is based on allocation groups (a type of subdivision of the physical volumes in ...
Category for file systems that are implemented in the Linux kernel. (Note: portable user space file systems which use FUSE or other such means should not be included.) (Note: portable user space file systems which use FUSE or other such means should not be included.)
