The inode is a data structure in a Unix-style file system which describes a filesystem object such as a file or a directory

The inode is a data structure in a Unix-style file system which describes a filesystem object such as a file or a directory. Each inode stores the attributes and disk block location(s) of the object's data. Filesystem object attributes may include metadata (times of last change, access, modification), as well as owner and permission data.

Directories are lists of names assigned to inodes. A directory contains an entry for itself, its parent, and each of its children.

Inodes after extending filesystem

If I make a ext4 filesystem and add about 20% of extra inodes, how would this effect the inode count if later I extend the filesystem? Would the extended filesystem also automatically add an extra 20% inodes? Or would it add a normal amount of…

It seems that the point of an imap is to hold points to individual inodes so that writes can be done in a really fast manner (can someone explain how this works as well?) but I was wondering what the point of having imaps that contain pointers to…
