I'd like to see the ability to run gjournal without reformatting. If you
could create a dummy file inside the filesystem, then use that area for
the journal, it might be possible. I'm sure that would let a lot more
people see if journalling is right for them.
I am not sure about gjournal internals but what if a system crash occurs
in the middle of a transaction and the fs gets corrupted and the data,
necessary to fix it is in the journal, but you cannot access the journal
because the file, which contains the journal, is on a corrupted fs?
You should better ask at the geom mailing list.
