I tried with +1, +2, and nothing, and I can't see any change !

But I'm in doubt :

when killing enbd-client, nda is marked faulty by enbd. So it remains in the array. But in this case, it must be totally removed from the array, as 
everything related to enbd is going to be removed from the kernel. This is a deadlock.

So i think that in this case, one have to make md to really unbind nda before suppressing it. setting SET_FAULTY is not sufficient. But how to do that 
? One have to do the same as mdadm --remove /dev/md0 /dev/nda before really destroy nda
