Oh, hmm. You have already a filesystem setup and everything on the "master"
mirror? If so, I'm not sure if you can do this without recreating the
gmirror, as the filesystem expects a provider of the master size, and
attaching a smaller slave which can't mirror all the master data won't really
work. The other way around is ofcourse much easier.
