[Lustre-discuss] New to lustre, client connection question

[Eric Mauger]

Hi,

I've built a small lustre system with 2 OST nodes, 1 MDS/MGT node and 
one client.
Each node has two nic. The first one (eth0) is used for administration 
purpose and the second (eth1)
is used for lustre interconnection.
I've installed the latest version (1.8.1) on x86_64 platforms running 
centos 5.4.
When I try to moun the fs on the client, I use the following command :

mount -t lustre 10.7.0.127 at tcp0:/lustre /mnt/lustre/

The lustre network is 10.7.0.0/24

On the MDS/MGT logs, I have :

mds kernel: LustreError: 120-3: Refusing connection from 195.220.11.120 
for 195.220.11.127 at tcp: No matching NI

The address 195.220.11.120 is on eth0 and I really don't understand why 
the connection seems to come from
this network instead of 10.7.0.0

I tried the lctl list_nids on all machines an here is the result :

[root at ost1 ~]# lctl list_nids
10.7.0.126 at tcp
[root at ost2 ~]# lctl list_nids
10.7.0.125 at tcp
[root at mds ~]# lctl list_nids
10.7.0.127 at tcp
[root at lustre-client ~]# lctl list_nids
10.7.0.120 at tcp

Any suggestions ?
