Hi Peter,
   If I understand right, even if I used FR1, it wont pass the test 
(unplugging the cable). Notice that Im not interested int hotplugging, but in 
hotUNplugging it as Michael Tokarev said: unplug the cable, linux starts 
using a degraded mirror, and later I can shutdown the server, plug the disk 
and let it resync.

Thanks,
