I noticed that you built your raid partitions on corresponding disk partitions. Why do that instead of making one monolithic raid volume and then partitioning that into the desired pieces? Since I already built my array, I don't want to dump, rebuild, and restore at this time. What I'd like to do is do two small (I don't know if they are small actually) to my system: 1. Adjust the partition table on each of the component disks so that I can assemble the drives from /dev/sd?1 instead of /dev/sd? 2. Adjust my /dev/md0 so that it is partitioned into /dev/md0_1 /dev/md0_2 or something of that ilk. I see now that I could have built it that way from the start, but is it too late to convert? Thanks!
