I don't think that hacking gmirror to move its metadata is a right
approach to the problem. It will make metadata detection complicated and
depending on some external knowledge. Why just not partition the disks
and not use gmirror on top of partition table? If partition will not use
the last sector of the disk, controller should be happy and gmirror
won't need any hacks.
