All of the log location info is zero here so you have no knowledge
of any existing log, so I would expect a "mount -o log" to create
a log normally.

Do you actually get an error when you try "mount -o log ..." ?

The "tunefs: Can't change size of non-in-filesystem log" message above
is also because there's no existing log info in the superblock to
change.
