Hi If i've understood correctly gmirror uses the last sector on the provider for a metadata. If one uses http://www.onlamp.com/pub/a/bsd/2005/11/10/ FreeBSD_Basics.html to setup a gmirror'ed system, that is haveing a fully used disk where the last sector is used (right?) and converting it to a gmirror, this will overwrite whatever is on the last sector, right? This will probably not be overwritten on a non-full fs, but if the fs gets full later, is there any risk that this sector get's overwritten? Does one have to shrink the fs/slice manually or something to make sure this does not happend? I haven't seen anyone mention this anywhere so im just curious to how it works Thanks Johan
