The e2fsprogs package contains a number of utilities for creating,
checking, modifying and correcting any inconsistencies in ext2, ext3,
and ext4 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), resize2fs to grow and shrink
unmounted filesystems, and most of the other core ext2fs filesystem
utilities.

You should install libext2fs2 to use tools that compile with ext2fs
features.
