What Is EXT4 File System and Why Need to Format Disk Partition as EXT4

The EXT4 (Fourth Extended File System) is a popular file system for Linux systems. It is the EXT3 file system successor and was released in 2006. One of the main improvements of EXT4 over its predecessor is its increased capacity, as it supports file sizes and volumes up to 16TB and 1EB (exabyte), respectively. In addition, EXT4 includes several other features that improve performance and reliability. These include:

  • Online defragmentation: EXT4 can defragment files while in use, improving the overall performance of the file system.
  • Faster file system checks: EXT4 uses a new data structure called the Flexible Block Group Descriptor, which allows for faster file system checks and reduces the downtime required for maintenance.
  • Extents: EXT4 uses extents to store file data, which can improve performance for large files by reducing the number of metadata updates required.
  • Multi-block allocation: EXT4 can allocate multiple data blocks at once, improving performance for certain types of file access.

There are several situations in which a Linux user may need to format a disk partition as EXT4:

  • Installing a new Linux operating system: If a user is installing a new Linux operating system, they may want to use the EXT4 file system for their root partition. This will allow them to take advantage of the improved performance and increased capacity offered by EXT4.
  • Upgrading from an older file system: If a user is currently using an older file system such as EXT3, they may want to upgrade to EXT4 to take advantage of its improved performance and increased capacity.
  • Changing the file system for a specific partition: A user may want to change the file system for a specific partition on their system, such as their home partition, to EXT4 for improved performance or increased capacity.
  • Repairing a damaged file system: If a file system becomes damaged, a user may need to format the partition as EXT4 to repair it. This will erase all data on the partition, so it is important to back up any important data before proceeding.
