I think the capability is in mdadm 3.2, a developer-only release about 4
days ago, or it's in Neil Brown's 3.2 devel branch. Take a closer look
at the list archives for the last few days.
As for using it, it'll be the usual syntax, e.g. `mdadm /dev/mdX --add
/dev/newdisc; mdadm /dev/mdX --grow --raid-disks=3`.
Hope this helps.
Cheers,
John.
