- Doug: How do I query the discovery setting? There is no "lnetctl show discovery" (should there be?). I tried "lnetctl set discovery" with no parameters and that core dumped (see previous section). From a usability perspective, there is no obvious way to get this information.
- Doug: I understand that Chris Morrone pushed for us to have "lnetctl set <key> <value>". That breaks from the original paradigm to follow which was done with the Linux "ip" command. It was designed to be: "ip <object> <action> <optional params>". So, it would be more logical to have: "lnetctl discover set 0/1" than "lnetctl set discovery 0/1". Then starting discovery can be: "lnetctl discover start <nids>". Looking for discovery status can be: "lnetctl discovery show". I found myself guessing at these commands as I have given here and had no idea to look at "set".
