Unless something's changed very recently then you can't grow a RAID-10
array (by adding disks anyway) - only RAID-1, RAID-5 and RAID-6 can be
grown in this way.
If you do want to grow it then the process will have to be backup,
recreate and restore. Otherwise you can set them up as a RAID-1 and
mount them as another filesystem.
