Quick Answer: What Is Tune2Fs in Linux?
Contents

Description. tune2fs allows the system administrator to adjust various tunable filesystem parameters on Linux ext2, ext3, or ext4 filesystems. The current values of these options can be displayed by using the -l option to tune2fs(8) program, or by using the dumpe2fs(8) program.

Which command is used to tune ext4 file system parameters?

The “tune2fs” command is used to change or modify tunable parameters on ext2, ext3 and ext4 type filesystems.

Which option to the tune2fs command sets the maximum mount count before the system will automatically run fsck on the partition on boot?

tune2fs can trigger a forced fsck on every reboot using the -c (max-mount-counts) option. This option sets the number of mounts after which the filesystem will be checked, so setting it to 1 will run fsck each time the computer boots.
