I found the answer to this question on Coraid's site soon after I
asked.

I added this to the "devices" section of lvm.conf:

    types = [ "aoe", 16 ]

After that, everything worked perfectly!

I've now got an operational setup with a single node.  Now I've just
got to see if I can get the other nodes configured.

Thanks for the help (and patience)!
