The fixit floppy, and a backup tape.  If your root file system is
still intact, you perhaps don't need the fixit floppy (since you can
boot single-user, and try to fix the problem).

There's an fsdb around (it went to /xperimnt in 2.1R and is in the
base system in the 2.2 development sources), but it's perhaps rather
tricky to use it.  Try if you can use alternate superblocks (fsck -b
32).
