I think you've not understand what I said :
I've a disk on target 0, one on target 1 and one on target 5
At boot time, t0 is assigned /dev/sda, t1 is assigned /dev/sdb and t5 is
assigned /dev/sdc
If i add a disk on target 3, it becomes /dev/sdc and t5 becomes /dev/sdd
If my t0 and t1 are mirrors (raid1)
If t1 goes on fire, t5 becomes /dev/sdb, so mdadd thinks it has to mirror t0 on
t5
