I'm not disagreeing, I'm only pointing out that it is possible and what the general fix looks like. We had a customer requirement to get it don= e that way, and at the time it was just the fastest way to code it. I'm a fan of moving discovery to user-land, alas I'm also a fan of fran= k words and right now the much hailed user-space discovery of RAIDs, partitions etc still has a couple of months to go to stabilize ;-) Sincerely, Lars Marowsky-Br=E9e --=20 High Availability & Clustering SUSE Labs, Research and Development SUSE LINUX Products GmbH - A Novell Business - To unsubscribe from this list: send the line "unsubscribe linux-raid" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
