softraid0: invalid metadata format
You filled the disk with random data, which is not a valid metadata
format...
I followed the FAQ,
http://www.openbsd.org/faq/faq14.html#softraidCrypto .
Sorry, I was hasty. You can also try creating smaller partitions.
16TB, 8TB,
etc. to see what works. That would be helpful information to have.
8Tb seems to be fine, 16 not so much. Ran into a weird issue where I
couldn't try with 12Tb.

Stupid me, I forgot that the softraid device was still attached.
12Tb, 14Tb and 15Tb works as well, 16 seems to be where it breaks.
