[lustre-discuss] error while configuring lnet

[Mannthey, Keith]

If you have ib0 device check dmesg for more hints on what is going wrong.

Thanks,
Keith

Hi,

Basically I am trying to add lnet. Deleting is just try whether it is happing or not.
Main is I want to add o2ib network. Which is giving error "invalid argument "
==================
[root at mds2 ~]# lnetctl net add --net o2ib --if ib0
add:
    - net:
          errno: -22
          descr: "cannot add network: Invalid argument"
================
I am really not able to understand what argument is invalid in my command.
I am able to ping ib0 network

Regards,
Parag

What are you trying to accomplish?

>From below:

10.1.1.205 at tcp<mailto:10.1.1.205 at tcp> is on 0 at lo not eno1 and in general you should not need the "-if" option to delete a fabric.

Try: # lnetctl net del --net tcp

Can you do a normal ping over ib0?

"dmesg" can sometime provide greater details about errors like this.

Thanks,
Keith
