Exactly! I don't want the overhead of writing two mirrors. Also, I want the "active" mirror to be on a separate controller.

although I can see with your configuration you could loose 2 drives and not loose any data..

I have a RAID 5 using the bulk of the drive space on the 3 drives. I used a small partition on each for the RAID1. Anyways, I've heard it's not possible to boot a RAID5 from GRUB. However, even if it were possible I'd rather run a RAID1 for the OS files.
I still haven't figured out how to remove one of the drives from the RAID1 and then add it as a spare. I've tried removing it and re-adding it but it always becomes a mirror again instead of a spare. Anyone know how to reconfigure this? It should be super simple but I can't find anything through Google on how to do this.
