Hi Eli,
Yes & no; part of my info is a bit rusty because I carried them from version
around 2.10. MR is now turned on by default.
But you'll need to have an IP setup on each IPoIB interface, and for all ib0 &
all ib1 interface, they should be in different subnet. Eg: all ib0 on
Hi Angelos,
Thanks for the answer!
According to the lecture Lauz just sent multirail is on by default no?
So I don't need to set IPs on each interface (using
interfaces/netplan/network scripts) just a single NID at the lnet level?
Thanks again,
Eli

Hi Eli,
I think you can leave out the IP so long as you specific the interface, but
IIRC you can't setup multirail via modprobe, you should setup Lnet using
lnetctl

Hey Lauz,
Thanks for the reply!
Indeed it sounds like multirail is what I am referring to (my wrong memory
of multirail was a failover technique allowing connection of both TCP and
IPoIB or multiple IPoIB between nodes at the same time), but I am still
left with a question.
In the modprobe
The limit of IPoIB is active/backup when using traditional bonding, however I
believe you are wanting to multirail your IB. This is achieved buy using
multiple LNet's (assuming it uses the same fabric), you should be able to
configure for active/active.
Hey everyone,
This is probably off-topic but I can't find any documents on the subject
and since Lustre uses IPoIB I suspect others here have dealt with this
question.
If I have a node connected with multiple IB links should each connected IB
port have it's own IP address or is there a way
