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.
