Filesystem Structures. To read an EXT2 inode we must look for it in the inode table. If, for example, the root inode number is 42, then we need the 42nd inode from the inode table. The root inode is for an EXT2 directory, in other words it's data blocks contain EXT2 directory entries.I'm trying to wrap my head around the EXT2 file system, but I can't find a single place that shows me the EXT2 file system in detail. What are the EXT2 file system structure details? Ask Question 1. The number of bytes per block is 1024n where n is given in the superblock and is a 32 bit integer. So in theory, a block could be ext2 filesystem superblock structure

Chapter 3. Disk Organization. An Ext2 file systems starts with a superblock located at byte offset 1024 from the start of the volume. This is block 1 for a 1KiB block formatted volume or within block 0 for larger block sizes. Note that the size of the superblock is constant regardless of the block size.

Structure of an Ext2 Filesystem. On disk, the Ext2 filesystem is organized as shown in the picture below: The first 1024 bytes of the disk, the boot block , are reserved for the partition boot sectors and are unused by the Ext2 filesystem. ext2 filesystem superblock structure
