This partition didn't grow for some reason...
gpart resize -i 1 mmcsd0s2
Should grow it...

I just recently rewrote crochet's autosize/growfs rc.d script to be
able to handle any partitioning scheme to grow /... You could try the
attached... just run: "growfs start" and it should run all the necesssary
commands...
