From the README:

Right now, e2fsck will reject an uncleanly unmounted ext3 partition.
However, if you umount an ext3 filesystem cleanly, you can fsck it using
a version of fsck which understands the journal flags: you'll want
e2fsprogs-1.17 or later, which you can get from the ext2 web pages at

        http://web.mit.edu/tytso/www/linux/ext2.html

You can now run e2fsck quite happily on the filesystem, *as long as the
filesystem was unmounted cleanly*.  If it wasn't, then you'll need to
get the kernel code to recover the journal from the disk by mounting the
filesystem (even a readonly mount will cause a journal recovery to
happen) and umounting it again (or, for the root filesystem, remounting
it readonly with "mount -o remount,ro /").
