tune2fs

Tune2fs is a command-line tool used in Linux systems to modify and adjust settings on ext2, ext3, and ext4 filesystems—these are common formats for organizing data on storage devices. It allows system administrators to customize parameters like how often the filesystem checks for errors, the maximum number of mounts before a check is needed, or other maintenance options. Essentially, tune2fs helps optimize and manage the health and performance of a storage device by adjusting its internal settings to suit specific needs or to improve longevity and reliability.
