I tried it with "label" in single user mode, but i do not get it work.
The error message is: "too few paramaters".

I also understand it that way. The problem is, or seems to be, "gmirror
label -v -b load mirror0 da0" does not work for me on a mounted device.
If i use another disk, da2 and da3, umount them, gmirror labeling will
work. 
So, in my understanding, i have to boot from another bootable device,
and set up gmirror on da0 (where / is sitting an waiting to get
mirrored) and da1 while these devices are not mounted.
