Ext2 file system the regular file system in Linux is Ext2 (Linux second extended file system), which consists of the following three parts: 1) super block: records the overall information of this file system, includes the total inode/block quantity, usage, remaining amount, and file system format and related information. 2) inode: records the attributes and permissions of a file (metadata). A file occupies one inode and records the block number of the file data. 3) block: because Ext2 is an inde
