Hi,<br>
<br>
We have a tcp1 config, but lnet.conf looks like this:<br>
<br>
net:<br>
- net type: tcp1<br>
local NI(s):<br>
- nid: <IP>@tcp1<br>
status: up<br>
interfaces:<br>
0: eth0<br>
<br>
replace <IP> with NID IP. I guess you need "- net type"
instead of just "- net".<br>
<br>
Cheers,<br>
Hans Henrik<br>

<div>Hi.</div>
<div><br>
</div>
<div>I've got an /etc/lnet.conf on a RockyLinux 9.4 client
running lustre 2.15.5-1.el9 which has this lnet.conf:</div>
<div><br>
</div>
<div>[root@stg-login-0 rocky]# cat /etc/lnet.conf <br>
net:<br>
- net: tcp1<br>
interfaces:<br>
0: eth0<br>
</div>
<div><br>
</div>
<div>Running systemctl start lnet just hangs forever, with the
syslog just showing</div>
<div><span
style="color:rgb(29,28,29);font-family:Monaco,Menlo,Consolas,"Courier New",monospace;font-size:12px;font-variant-ligatures:none;background-color:rgba(29,28,29,0.04)">Sep
13 15:31:35 stg-login-0 systemd[1]: Starting lnet
management...</span><br>
</div>
<div><br>
</div>
<div>and its actually the below which hangs:</div>
<div>[root@stg-login-0 rocky]# /usr/sbin/lnetctl import
/etc/lnet.conf<br>
</div>
<div>i.e. module load and lnet configure work OK.<br>
</div>
<div><br>
</div>
<div>However it looks like it autoconfigured an interface on tcp
(not tcp1):</div>
<div>[root@stg-login-0 rocky]# lnetctl net show<br>
net:<br>
- net type: lo<br>
local NI(s):<br>
- nid: 0@lo<br>
status: up<br>
- net type: tcp<br>
local NI(s):<br>
- nid: 10.179.2.45@tcp<br>
status: up<br>
</div>
<div><br>
</div>
<div>So:</div>
<div>1. How can I debug this hanging please?</div>
<div><br>
</div>
<div>2. Do the client and server NIDs need to be in the same
IPv4 subnet? I have a client NID of 10.179.2.45@tcp1 and a
server NID of 10.167.128.1@tcp1, with IP routing between them
such that icmp ping works between them, is that OK?</div>
<div><br>
</div>
many thanks for any help!
