[lustre-discuss] Lustre Client pinned to use specific NIC on host

[Sonia Sharma]

Hello Dear Lustre Community

I was wondering if there is some setting/way to make a Lustre Client use only a specific NIC to route its LNet messages from even when multiple NICs on that host are configured with the same LNet network.

For example, let’s say I have a host with this below LNet configuration, then is there a way that I can have the Lustre client to use only “10.30.201.26 at tcp” for all its communication

[node1]# lnetctl net show
net:
    - net type: lo
      local NI(s):
        - nid: 0 at lo
          status: up
    - net type: tcp
      local NI(s):
        - nid: 10.30.201.26 at tcp
          status: up
          interfaces:
              0: enp1s0
        - nid: 10.30.201.10 at tcp
          status: up
          interfaces:
              0: enp1s0:10269
        - nid: 10.30.202.241 at tcp
          status: up
          interfaces:
              0: enp1s0:10257

Best regards
Sonia
