[Lustre-discuss] LNET over multiple NICs

Hi all!
I have the following setup:
* 4 x OSS servers with 2 x 10GbE
* 4 x clients with 2 x 10GbE (these are kind of NFS servers to
redistribute filesystem to all other clients)
I would like to use multi-rail LNET over Ethernet instead of bonding
for performance reasons (if there are any). I am using 192.168.110.x for
one adapter and 192.168.111.x for another one.
Mounting filesystem on the clients as:
mount.lustre 192.168.110.11 at tcp0,192.168.111.11 at tcp1:/lustre /mnt/lustre
But all LNET traffic from any client goes to the 192.168.110.11 at tcp0
only, despite of current load on the nid. lctl ping is working fine for
both nids.
I know that I can mount 2 clients to tcp0 and 2 other to tcp1, but
would like to use both interfaces on each client for performance
reasons.
I've been looking into Lustre manual and found multi-rail for
Infiniband only.
I wonder what is recommended now for LNET over Ethernet with multiple
adapters, where fault-tolerance is less important than performance?
Thank you,
Alex.
