No, it clearly says tunefs CANNOT be run on an active filesystem.
Then it says, in order to change an active file system you have to first
make it a NOT active filesystem - eg make it read-only or just unmount it.

That means it is a BUG that it won't work on an active files system - eg
that someone should fix this defficiency and make it so it will work
on an active filesystem. The man writer thinks it 'should' be able to
work that way.
