How do you create several RAID devices if you only have 2 drives? Is there a way to create virtual RAID sets? That sounds too scary.
You create raid devices over partitions that don't span the entire drive.
Why would this be a configuration that someone would want to do? So you can have both a 0 (performance) and 1 (redundancy) on the same physical drives, depending on your partition? Just seems odd.
Thanks, Scott
What if you wanted /boot and / to be on a raid1 for redundancy, but you wanted a scratch directory on raid 0 for the speed, maybe for video editing or other I/O intensive operation? If you didn't care that the scratch directory failed on a drive fail, you could get back and running with a reboot and re-creating the filesystem on the scratch directory.
