Inodes exist in a static form on the disk. The kernel reads them into in-core inodes and modifies them. Disk inodes consists of the following fields: 1. Owner information: ownership is divided into a user and a group of users. Root user has access to all the files. 2. File type: it states whether a file is a normal file, a directory, … See more In UNIX, the data in files is not stored sequentially on disk. If it was to be stored sequentially, the file size would not be flexible without large fragmentation. In case of sequential storage, the inode would only need to … See more Directory files have entries of sub directories and files that reside inside them. Directory files have the mapping of a file name and its inode number. One directory entry takes … See more The contents of the super block are: 1. size of the file system. 2. number of free blocks in the file system. 3. list of free blocks in the file system. 4. pointer to the next free block in the free blocks list 5. size of the inodes … See more Algorithm namei (name to inode) is used for converting a path to an inode number.
