Description:

The e2fsprogs package contains a number of utilities for creating,
checking, modifying, and correcting any inconsistencies in second
extended (ext2) filesystems. E2fsprogs contains e2fsck (used to
repair filesystem inconsistencies after an unclean shutdown), mke2fs
(used to initialize a partition to contain an empty ext2 filesystem),
debugfs (used to examine the internal structure of a filesystem, to
manually repair a corrupted filesystem, or to create test cases for
e2fsck), tune2fs (used to modify filesystem parameters), and most of
the other core ext2fs filesystem utilities.

You should install the e2fsprogs package if you need to manage the
performance of an ext2 filesystem.
