Hello,<br>
I am trying to deploy a multi rail configuration on Lustre 2.10.0 on
RHEL73.<br>
My goal is to use both the IB interfaces on OSSes and client.<br>
I have one client and two OSSes and 1 MDS<br>
My LNet network is labelled o2ib5 and tcp5 just for my own
convenience. What I did is to modify the configuration of
lustre.conf<br>
<br>
options lnet networks=o2ib5(ib0,ib1),tcp5(enp1s0f0)<br>
<br>
lctl list_nids on either hte OSSes or the client shows me both local
IB interfaces:<br>
<br>
<b>172.21.52.86@o2ib5</b><b><br>
</b><b>172.21.52.118@o2ib5</b><br>
172.21.42.211@tcp5<br>
<p>anyway I can't run a LNet selftest using the new nids, it fails.</p>
Seems like they are unused.<br>
Any hint on the multi-rail configuration needed?<br>
What I'd like to do is use both InfiniBand cards (ib0,ib1) on my
two OSSes and on my client to leverage more bandwidth usage<br>
since with only one InfiniBand I cannot saturate the disk
performance.<br>
thank you
