I finally found the solution to this and wanted to pass it along.

RDMA does not work with "cache=none".  There is an auto-detect routine
deep within the python code that is supposed to switch this to
writeback, but it doesn't detect RDMA.  Luckily, the VM's that start
on this set of compute nodes are fine with "cache=unsafe" so I am
using that instead.

I can send a patch to detect RDMA if this is still a problem in Grizzly.

Thanks,
Mark
