In my opinion, the brief excerpt from the book that you can find on the O'Reilly sit I think -- or maybe it's a seperate article -- is a great intro to mdadm. It's all you need to get started. Couldn't be easier. My suggestion is to make some practice partions and fool around with the commands for a few hours. Mdadm is great. - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
