Hi,<br>
<br>
Thanks for your quick response. <br>
<br>
My /etc/modprobe.d/lustre now contains<br>
<br>
options lnet networks=tcp0(eth0),tcp1(eth1)<br>
<br>
I updated the partitions with the following:-<br>
<br>
<a class="moz-txt-link-abbreviated" href="mailto:mgsnode=172.16.0.57@tcp,172.17.11.250@tcp1">mgsnode=172.16.0.57@tcp,172.17.11.250@tcp1</a><br>
<br>
On both of the MDT's lctl list_nids reports (note they have the above
lnet entry in their /etc/modprobe.d/lustre file):-<br>
<br>
172.16.0.51@tcp<br>
172.17.11.252@tcp1<br>
<br>
On clients, for either network, they do not have the lnet entry and
lctl list_nids reports on the local machine ip address. However,
clients on the tcp0 network can mount the lustre partition. Clients on
the tcp1 network cannot mount via the tcp1 IP address but can via the
tcp network (with a another machine routing the traffic).<br>
<br>
Do I need the same lnet module entry everywhere to make this work ?<br>
<br>
Regards<br>
<br>
Phil.<br>

I've tried the following:-
1. Create /etc/modprobe.d/lustre that contains
options lnet networks=tcp0,tcp1

This probably needs to be like:
options lnet networks=tcp0(eth0),tcp1(eth1)
</pre>

<pre wrap="">2. Used tunefs.lustre to specify the ip address of both interfaces of
the MGS/MDT is on, i.e. tunefs.lustre --eraseparams
--mgsnode=<net1>@tcp0,<net2>@tcp1 /dev/md5
3. Started up lustre
The clients could connect on network tcp0, but the clients that would
connect via the IP address of network tcp1 could not.
What am I missing ?
Thanks
Phil.
