EXT4 Deprecates Its Journaled "data=journal" Mode
EXT4 file-system deprecates journaled mode of the "data=journal" mount option, to be removed in 2028.
Intelligence analysis by Qwen 2.5 (3B)
EXT4 file-system deprecates its journaled mode, which is planned for removal in 2028, to ensure data integrity and safety.
EXT4 file-system used to write all file data and metadata to a journal before saving it to the main file-system. This helps ensure data safety, but it slows down writing files.
Analysis
{"heading_1":"EXT4 Data Journaling","content_1":"EXT4 file-system uses data=journal mode to ensure data integrity and safety by writing all file data and metadata to the journal before committing to the main file-system. This mode is deprecated and will be removed in 2028.","content_2":"The data=journal mode is great for those very concerned about data integrity but comes with significant hits to write performance compared to the default ordered (data=ordered) mode or data=writeback.","content_3":"The EXT4 data=journal feature is deprecated and support for it will be removed in early 2028 following the 2027 Linux LTS kernel version."}
Key points
- EXT4 file-system deprecates its journaled mode
- Data=journal mode will be removed in 2028
- Deprecation affects systems concerned about data integrity and performance
The removal of data=journal mode will improve write performance for systems using EXT4.
Systems that rely on data=journal mode for data safety may experience issues during system crashes or power loss.
