Has anyone tried gmultipath under 8.1-RELEASE/amd64 yet? This is my
first attempt at multipathing so it is possible I'm doing something
wrong but anyways:

I'm wondering what is going on with the "Unknown verb add" and why is
it only listing da1 in the components? Does the disk need to be in a
particular state (unpartitioned, glabel, etc...) or does it not
matter?
