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. -- Ulf Lilleengen
