Incidentally, you don't have to stop the storage server nodes. Tahoe
will tolerate shares being deleted out from under it just fine.

You can use "tahoe debug dump-cap $FILECAP" (or the "More Info" button
on the web interface) to learn the "storage index" for a given file.
Then you can locate the share files by running "tahoe debug find-shares
$STORAGEINDEX $BASEDIRS.." on each storage server: this will emit a list
of filenames to stdout. Just delete the files it lists (and their
$STORAGEINDEX parent directory, if you want to save a tiny extra bit of
space).
