tune2fs-Adjusting System parameters

The TUNE2FS command allows the system administrator to adjust the parameters in the "ext2/ext3" file system. Under Windows, if there is an unexpected power outage, the system self-test will appear on the next boot. The Linux system also has a file system self-test, and it is possible to define self-test cycles and methods by TUNE2FS commands.
