If you wanted a more defined partition scheme for your RAID you might as well just partition the physical disks and create a raid with those partitions. For example /dev/sda /dev/sdb /dev/sda and /dev/sdb will be partitioned into two primary partitions split down the fictional cylinders. /dev/sda1 /dev/sda2 /dev/sdb1 /dev/sdb2 We can create one RAID 1 if we like using /dev/sda1 and /dev/sdb1 md0 We can create another using /dev/sda2 and /dev/sdb2. md1 We can go further and partition md0 or 1 if we choose, but I don't see why. Just complicates things further than they need to be. I think it is really just a matter of personal preference. ~M
