1) No this is just a new testbed.

2) I am not even to the mount stage yet.  The errors in the log I am
seeing are when I start the management daemon.  I went through the
process of creating the volume but still no dice.

  gluster peer probe
  gluster volume create gtest replica 2 transport rdma
  gluster volume start gtest

But the volume is not starting correctly,

# gluster volume status gtest
Brick status for volume: gtest
