Hmm, that man page says that Debian jessie has version 3.3.2-5 and
still it says:

Grow

[…]

    …changing the chunk size and layout for RAID 0,4,5,6,10 as well
    as adding or removing a write-intent bitmap.

So is the man page wrong?

Admittedly until I looked I thought RAID-10 couldn't be reshaped at
all in any way. And now I don't know at all. :)

Cheers,
Andy
