How are inodes created?
How inodes are created and even if they are created, depends upon the specific file system. Several file systems create all of them when the file system is created resulting in a fixed number of inodes. For example, ext3 is a file system that does this. The result is that the file system has a fixed number of files that can be stored. Yes – it’s actually possible to have capacity on the storage and not be able to store any more data (it doesn’t happen often but it’s theoretically possible). If you need more inodes you have to remake the file system losing all data in the file system. One way around the trap of a fixed number of inodes is some file systems use something called extents and/or dynamic inode allocation. These file systems can basically grow the file system and/or increase the number of inodes. Inodes aren’t something mysterious that you should tiptop past but rather something that is part of Linux. For example, you can look at the inode for your files by simply using the “-i” option with “ls”. For example,
