Details after the grow:

md126 : active (auto-read-only) raid6 sdj1[2] sdl1[3] sdf1[9] sdn1[11] (S) sdi1[1] sdg1[10] sde1[8] sdh1[0] sdk1[4] sdo1[12]

 Delta Devices : 1, (8->9)

Please post mdadm --examine from all component drives, but I'd say if you try to access your data everything should be there and the grow should continue once the array is not auto-read-only anymore (guess from my side though).

If you look here:

http://www.linuxquestions.org/questions/linux-server-73/raid-5-mdadm-grow-interrupted-what-to-do-next-602671/

It's a bit old, but here there is also "delta devices" and on the component drive there is a "reshape position". If you see that on your component drives as well, just try accessing the array and see if the reshape continues.
