I am setting up a linux server with two drives in an mdadm created raid 1. All the online help I fine says to create your partitions and then create an md0 raid volume using something like sda1 and sdb1 for the raid. So my question is, what if drive sda goes down...how will drive sdb boot up?
I want two 100% identical drives so that if one fails, I can install a new drive, repair and run without any loss of data.
