I use the whole disk to gmirror setup on all my servers.

And one day i thought i could try the gpart stuff.
I also saw the message at startup, and disgarded it.
This was on 8.1

But when i did an upgrade to 8.2 later on, the system could not boot.
So i had to find another way.

So i would not do it like you do now, it could turn against you in the long run.
The thing i did was to mirror each partition.
Like so
that way it worked.
Do not forget to make your second disk bootable also
