inode

inode

A data structure holding information about files in a Unix file system. There is an inode for each file and a file is uniquely identified by the file system on which it resides and its inode number on that system. Each inode contains the following information: the device where the inode resides, locking information, mode and type of file, the number of links to the file, the owner's user and group ids, the number of bytes in the file, access and modification times, the time the inode itself was last modified and the addresses of the file's blocks on disk. A Unix directory is an association between file leafnames and inode numbers. A file's inode number can be found using the "-i" switch to ls.

inode

(Index NODE or Identification NODE) One index entry in a Unix file system. It contains a unique number (the i-number), the file's attributes, including name, date, size and read/write permissions, and a pointer to the file's location. It is the counterpart to the FAT table in the DOS/Windows world. See handle and FAT.

Holz and Raynal [15], discovered that the easiest way to tell whether you are inside a chroot() environment is to run an ls-lia command on the root directory, and look at the inodes of '.' and '..' directories.
However, the more the files are created, the less the transaction rates are produced because the larger number of inodes is allocated in the same directory, resulting in the memory pressure.
Each node maintains file metadata including file name, inode number, and a range of data.
With testing of the end-to-end network elements successfully achieved, 60 per cent of the installed Fujitsu MSANs are now connected to 21CN fibre rings, Metro nodes and iNodes.

In a UNIX environment the file system structure is managed by a protocol called inodes. Mac computers have used inodes as a sectoring protocol since the 2001 operating system OS X was released, and their own proprietary system for OS 9 and all earlier operating systems.
* Besides data, file system metadata (inodes and unodes) is cached on both the client side and the server side.
In file systems, metadata (e.g., directories, inodes, and free block maps) gives structure to raw storage capacity.
Bonnell argues that Salutati considers otium and negotium to be inodes of life, and the active and contemplative lives to be stages in the interior ascent of the soul.

In particular, SVIDContainer inherits operations from ObjectContainer to manage a table of open MemoryObjects and from its superclass UnixContainer to read and write disk inodes, while SVIDInode inherits most of its operations from UnixInode.
