There is a bug that prevents enabling journaling on a mounted filesystem. 
So for now you can't enable it on /.  I see that you have a large / volume 
but in general I would also suggest people not enable suj on / anyway as 
it's typically not very large.  I only run it on my /usr and /home 
filesystems.

I will send a mail out when I figure out why tunefs can't enable suj on / 
while it is mounted read-only.

Thanks,
Jeff
