geom(4)'s gmirror(8) class metadata structure has been
rev'd from v3 to v4. If you update across this point and
your metadata is converted for you, you will not be easily
able to downgrade since the /boot/kernel.old/geom_mirror.ko
kernel module will be unable to read the v4 metadata. You
can resolve this by doing from the loader(8) prompt:
set vfs.root.mountfrom="ufs:/dev/XXX"
where XXX is the root slice of one of the disks that composed
the mirror (i.e.: /dev/ad0s1a). You can can than rebuild
the array the same way you built it originally.
