[lustre-discuss] error while configuring lnet

[Parag Khuraswar]

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 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
