Hi,
Since the data is available in two places on a RAID1 array does the code in any way make use of that for improved performance by reading (different) data form both disks at the same time? Or is the one disk simply a slave that just receives copies of the data and is never really read from at all?
reads are distributed to both drives. the kernel raid implementation is considerably more sophisticated about this than the typical bios/driver based fake raid.
