I don't know why this is in the man page, last time I read it (some years ago)
it was not in there.
You can use the rebuild command also on non-raid controllers, at least it was
possible for me when I did some tests about 3 months ago.
As I can see you're considering gmirror, perhaps that's the better solution
for you. In all cases, simulate a drive failure, so you do know what to do
when one drive really fails.
