You are writing past the end of the partition. ;)

Note that disklabel on ccd returns a "default" label with only `c' if
there is no disklabel on the array, but will use one if it exists in
the first few blocks of the ccd (which means the first few blocks of
sd0h in your case).

Your problem is most likely because ccd is using the disklabel you
edited when you had a slightly larger array (because of different
interleave).
