If none of the possible superblocks are valid when using mke2fs -b
<NNN>, there's a good chance that your partition table (or LVM
metadata) has gotten corrupted.  You should definitely check to make
sure the partition setup is sane before trying to use mke2fs -S.

It's also true, as Andreas has stated, that with the large number of
new file system options and layouts with ext4, mke2fs -S is much more
hazardous unless you __really__ know what you are doing.  It would
probably be a good idea to have some warning messages to that effect
in the man page.
