The Handbook chapter on gmirror talks about the problems with GPT and
GEOM metadata. In short: right now, they conflict. It's possible to
mirror GPT partitions, but be aware that if you mirror more than one
partition on a drive, a rebuild after replacing a drive could thrash
the heads as mirrors are rebuilt simultaneously.

So,
gmirror+GPT=conflict on last sector
GPT+gmirror = hardrive head kill
nice...
So, for no more than 2TB disks the best way to go is GMIRROR of the
drive +PARTITION on top of it?
Or maybe there is a way to instruct gmirror do rebuild only what i say
(manual rebuild) ?
