According to the man page and numerous examples I've found, you can do this with: mdadm --add /dev/md0 /dev/sdd the catch is that all the examples I've seen were for recovering a RAID-5 (removing a failed device then adding one). Does anyone know if this will work without destroying the existing data on a RAID-0? Thanks in advance!
