What is the EXT4 file system

EXT4 (the fourth extended file system) is the file system used in Linux, and it is the successor to ext3. EXT4 is a more significant improvement to EXT3, many of which were initially developed by the Cluster file system from 2003 to 2006 to expand storage limits and improve performance. 

However, due to stability considerations, some Linux kernel developers do not accept extensions to EXT3. They suggest forking the source code of EXT3 and renaming it to EXT4. Then the EXT3 file system maintainer announced a new plan for EXT4 in 2006.

Main Features of EXT4:

  • Larger file system/file size. 

EXT3 supports a maximum file system size of 16TB and a maximum file system of 2TB, while EXT4 supports a maximum of 1EB (1EB = 1024PB = 1024 * 1024TB = 1024 * 1024 GB) file system size and maximum file size is 16TB, because EXT4 adds 48 bits block addressing. (1EB = 1024PB = 1024 * 1024TB = 1024 * 1024 GB)

  • More sub-directories

EXT3 currently supports only 32,000 sub-directories, while EXT4 removes this limitation and theoretically supports an unlimited number of sub-directories.

  • Log verification function

The log is the most commonly used structure of the file system. The log is also easily damaged, and recovering data from the damaged log will cause more data damage. 

EXT4 adds a check function to the log data. The log check function can quickly determine whether the log data is damaged. And EXT4 merges the two-stage logging mechanism of EXT3 into one stage, which improves performance while increasing security.
