I use the whole disk to gmirror setup on all my servers.=0A=
=0A=
And one day i thought i could try the gpart stuff.=0A=
I also saw the message at startup, and disgarded it.=0A=
This was on 8.1=0A=
=0A=
But when i did an upgrade to 8.2 later on, the system could not boot.=0A=
So i had to find another way.=0A=
=0A=
So i would not do it like you do now, it could turn against you in the long=
 run.=0A=
The thing i did was to mirror each partition.=0A=
Like so http://unix-heaven.org/node/24=0A=
that way it worked.=0A=
Do not forget to make your second disk bootable also=0A=
=0A=
