Comment 9 for bug 1831130

Hi Elio,

It seems that your interfaces used for datanetwork are not connected between compute-0 and compute-1. Your
network topology is following:

+++++++++++++++++++++++++ +++++++++++++++++++++++++
+ compute-0 + + compute-0 +
+ + + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + data enp134s0f0 + + data enp134s0f0 + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + mgmt enp134s0f1 +++++++++++++++++ mgmt enp134s0f1 + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + + +
+++++++++++++++++++++++++ +++++++++++++++++++++++++
                           Figure 1

The enp134s0f0 on compute-0 and compute-1 should be connected physically. You can connect them by following methonds:
   1. connect them by cable.
   2. connect them to the same switch.
After you connect them physically, the network topology should be like following:

+++++++++++++++++++++++++ +++++++++++++++++++++++++
+ compute-0 + + compute-0 +
+ + + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + data enp134s0f0 +++++++++++++++++ data enp134s0f0 + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + mgmt enp134s0f1 +++++++++++++++++ mgmt enp134s0f1 + +
+ +++++++++++++++++++ +++++++++++++++++++ +
+ + + +
+++++++++++++++++++++++++ +++++++++++++++++++++++++

You can check the connectivity between them by the following commands:
   on compute-0
      sudo ifconfig enp134s0f0 192.168.50.5/24 up
      ifconfig enp134s0f0
   on compute-1
      sudo ifconfig enp134s0f0 192.168.50.6/24 up
      ifconfig enp134s0f0
      ping 192.168.50.5
