Dunno about current versions, but IIRC some earlier versions of
dump(8) could handle even a badly-corrupted FS.  No harm in trying,
since it will not try to write anything to the FS being dumped.  Of
course, you need to find a place to dump it to (and I would _not_
advise piping the output into restore(8) in this kind of situation
-- save the dumpfile itself somewhere in case you find yourself
needing to hack on restore(8) to extract files from it).
