By the way, you don't really need raid10 for swap. Built-in linux swap code can utilize multiple swap areas just fine - mkswap + swapon on multiple devices/files. This is essentially a raid0. For raid10, one thing needed is the mirroring, with is provided by raid1. So when you've two drives, use single partition on both to form a raid1 array for swap space. If you've 4 drives, create 2 raid1 arrays and specify them both as swap space, giving them appropriate priority (prio=xxx in swap line in fstab). With 6 drives, have 3 raid1 arrays and so on... This way, the whole thing is much simpler and more manageable. /mjt - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
