The advantage of this is that we can add more disks to the whole > RAID set with no downtime Off-topic, but when you say add more disks, do you mean for the purpose of replacing failing disks or for expanding the array? I'm curious because on initial reading I read it to mean expanding the storage capacity of the array but thought it was currently not possible to expand a mdadm RAID 0 non-destructively.
