You can't increase the number of active devices in a RAID-5 (mdadm)
array because the distribution of data and parity is set when the
array is first created. To increase the capacity of the array you
would need to increase the capacity of all of the constituent
devices, "grow" the array to take up the extra space and then resize
the hosted filesystem.
