:I think I've narrowed the problem down to a repeatable thing that you
:don't have to reboot over:
    I am going to attempt to reproduce the problem with VN-based disks,
    but I'm no vinum expert and I can't guarentee anything.  If I can
    reproduce it I can probably fix it.  I far prefer a hardware raid
    solution (like the 3ware, which we support very well).
