man e2fsck

e2fsck is used to check a Linux second extended file system (ext2fs).
E2fsck also supports ext2 filesystems countaining a journal, which are
also sometimes known as ext3 filesystems, by first applying the journal
to the filesystem before continuing with normal e2fsck processing.
After the journal has been applied, a filesystem will normally be
marked as clean. Hence, for ext3 filesystems, e2fsck will normally run
the journal and exit, unless its superblock indicates that further
checking is required.
