Please see the manpage: | f...@host:~$ man mdadm | grep 'creating a RAID5' -A4 | When creating a RAID5 array, mdadm will automatically create a degraded | array with an extra spare drive. This is because building the spare | into a degraded array is in general faster than resyncing the parity on | a non-degraded, but not clean, array. This feature can be overridden | with the --force option. HTH, Flo
