What is inode?

An inode (index node) is simply a data structure that describes a specific file or a reference on the file system and has the directory entry acting as its storage. Inodes direct to several blocks that comprise an archive and contains every administrative data that are needed for accessing a file.

The Inodes stores the metadata of every file in the form of table structures. For instance, when working on a program that classifies a file by its name, the system searches into the directory entry file where it can be traced and bring it to the corresponding inode. It, therefore, gives the system the information and file data required when performing an operation or a process.

One of the most things to understand inode usage is where it is stored. Inodes are located adjacent to partition opening and serve as the storage of specific file information apart from the file name itself. For instance, all Linux directory files include an inode number and a filename so that users can easily retrieve all the metadata for a specific file by referring to the inode number.

For easier retrieval, the inode number and filenames have a separate link and index to the inode, and this you can easily link the metadata denoting the file. Moreover, the different storage makes it possible for several file names relating to a single inode or a piece of data.

Inode usage

Every inode is used to store the disk block locations and the attributes of the data of the object. Note, the file-system characterizes metadata, which acts as the indication of the time of last modification, access, changes as well as the file permission and owner of the data.

What is an inode number? Each inode in Linux structure has a unique number that is identified with it, which is also known as the index number.

Inodes have the following features:

  • Number of links
  • Owner
  • Size
  • The file type
  • Time/Data
  • Location in the disk
  • Access control /the permissions
  • Extra metadata concerning a file

How do the Inodes function?

Whenever a new file is created, it is usually assigned to an inode’s number and a file name and stored as unique entries in the directory. Remember that one way of exhausting your space on your file system is having all your Inodes in use. It means that even if you have adequate free space on a disk, it won’t be possible to create additional new files. When all inodes in your file system are in use, it can result in a sudden stop of your system.
