[lustre-discuss] Announce: Lustre Systems Administration Guide

[Arman Khalatyan]

Hello,
I am looking for some simple routing examples on ib0 to tcp.
All examples in the documentation are based on OPA or Melanox.
Found some inconsistency in the manual routing part:
http://wiki.lustre.org/LNet_Router_Config_Guide
section:ARP flux issue for MR node
The Ethernet part is missing in the examples it states " Below is an
example setup on a node with 2 Ethernet, 2 MLX and 2 OPA interfaces"
but examples are only with 4 interfaces described.


thank you beforehand,
Arman.
