This looks like 200 GB to me, for small values of 200.

That's puzzling.  I've never seen this before.  What version of
FreeBSD are you using?  Try:

  ktrace -i newfs /dev/vinum/data

This will create a file ktrace.out.  Look at it with:

  kdump | less

Look for the message in the output (it'll be there) and show the ioctl
call immediately before (if it's there).  Also check if there's any
message in dmesg output or /var/log/messages.  Otherwise I have
alternative tricks up my sleeve.
