During a resync (after an unclean shutdown) the devices are indistinguishable. RAID1 reads all drives and if there is a difference it chooses one data block to write to the others - always the one with the lowest index number. So with md or LVM it is the same: first "first" is "copied" to the "second". NeilBrown > but LVM RAID seems to hide those files > when leveraging the MD code.
