I just moved my RAID 1 array to a new server and I did the mistake of moving only one disk at first to make sure that I would still have a copy on the other server in case the new one couldn't read the array for some reason. When I added the second disk it mark it as faulty or something so I tried to remove it from the array and re-add it but it added a spare drive instead. So now my array is running in degraded mode, what can I do to so the second drive resync with the other one?
