<div class="moz-cite-prefix">here is my setup<br>
</div>
<div class="moz-cite-prefix">
<ul>
<li>MDS is on tcp0</li>
<li>client is on tcp0 and o2ib0</li>
<li>OSS is on tcp0 and o2ib0<br>
</li>
</ul>
</div>
<div class="moz-cite-prefix">The problem is that the MDS is
discovering both the lustre client and the OSS as well over o2ib
and it should not because the MDS has only one ethernet interface.
I can see this from lnetctl peer show. This did not happen prior
to upgrading to Lustre 2.12.0 from 2.10.5</div>
<div class="moz-cite-prefix"><br>
</div>
<div class="moz-cite-prefix">so I tried to debug with lctl ping from
the MDS to the lustre client</div>

<div>Hi Riccardo,</div>
<div><br>
</div>
<div>It's not LNet Health. It's Dynamic Discovery. What's
happening is that 2.12 is discovering all the interfaces
on the peer. That's why you see all the interfaces in the
peer show.</div>
<div><br>
</div>
<div>Multi-Rail doesn't enable o2ib. It just sees it. If the
node doing the discovery has only tcp, then it should
never try to connect over the o2ib. <br>
</div>
<div><br>
</div>
<div>Are you able to do a "lnetctl ping 172.21.48.250@tcp"
from the MDS multiple times? Do you see the ping failing
intermittently?</div>
<div><br>
</div>
<div>What should happen is that when the MDS (running 2.12)
tries to talk to the peer you have identified, then it'll
discover its interfaces. But then should realize that it
can only reach it on the tcp network, since that's the
only network configured on the MDS.</div>
<div><br>
</div>
<div>It might help, if you just configure LNet only, on the
MDS and the peer and run a simple</div>
<div>lctl set_param debug=+"net neterror"<br>
</div>
<div> lnetctl ping <></div>
<div>lctl dk >log</div>
<div><br>
</div>
<div>If you can share the debug output, it'll help to
pinpoint the problem.</div>

My problem is related to Lnet Network Health feature: <br>

the lustre MDS and the lsutre client having same version
2.12.0 <br>
negotiate a Multi-rail peer connection while this does not
happen with <br>
the other clients (2.10.5). So what happens is that both
IB and tcp are <br>
being used during transfers.<br>
tcp is only for connecting to the MDS, IB only to connect
to the OSS <br>
anyway Multi-rail is enabled by default between the
MDS,OSS and client. <br>
This messes up the situation. the MDS has only one TCP
interface and <br>
cannot communicate by IB but in the "lnetctl peer show" a
NID @o2ib <br>
shows up and it should not. At this point the MDS tries to
connect to <br>
the client using IB and it will never work because there
is no IB on the <br>
MDS.<br>
MDS Lnet configuration:<br>
<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: 172.21.49.233@tcp<br>
status: up<br>
interfaces:<br>
0: eth0<br>
<br>
but if I look at lnetctl peer show I See<br>
<br>
- primary nid: 172.21.52.88@o2ib<br>
Multi-Rail: True<br>
peer ni:<br>
- nid: 172.21.48.250@tcp<br>
state: NA<br>
- nid: 172.21.52.88@o2ib<br>
state: NA<br>
- nid: 172.21.48.250@tcp1<br>
state: NA<br>
- nid: 172.21.48.250@tcp2<br>
state: NA<br>
<br>
there should be no o2ib nid but Multi-rail for some reason
enables it.<br>
I do not have problems with the other clients (non 2.12.0)<br>
<br>
How can I disable Multi-rail on 2.12.0 ??<br>
<br>
thank you<br>
