I think what you've done is created only one partition per disk, and made those partitions into a RAID set. That's not wrong, but it's not the same thing. Non-partitionable RAID sets such as the one you've created are the most common configuration for software RAID. Hardware RAID volumes are almost always the partionable type. > Is the the proper way to configure software raid? "Proper" is relative to its fitness for a specific purpose. As you haven't indicated a specific purpose, "proper" doesn't have any real meaning. The array you've created will work, and it will protect your data from loss due to the failure of a single disk. You need to make sure your "root" mail is delivered to someone who will read it in a timely manner, or else that protection is not useful. The array's performance will be relatively lower than a single-drive configuration or a RAID10 configuration, but that may be acceptable for bulk storage. The array will not protect you from filesystem corruption or from accidental deletion. Subject to those and other limitations, your array seems more or less proper.
