It's definitely not impossible, since I did it with a stock 7.2 system and had
the config set up during the initial install. I had first tried it after I
installed but could not get it to come up properly during boot. I then redid
my install, told it to configure mirroring during boot, and it all worked.
7.2, of course, uses Grub by default.
Here's the fdisk info and files that I was using before I shut that system down:
