Re: gmirror + subset of partitions gjournal'd, autosync setting?

1. Is that recommendation a must or a nice-to-have? What are the actual 
consequences of not taking that advice?


2. In a case like mine, the non-journaled partitions need 
autosychronization enabled to benefit from being mirrored, right?

Can no one help me with this question?

Are you aware of the freebsd-fs list?  freebsd-questions is mainly for
generic How do I use ls(1)? questions.
