Our Lustre filesystem is currently set up to use the o2ib interface only-
all of the servers have
options lnet networks=o2ib0(ib0)
We've just added a Mellanox IB-to-Ethernet gateway and would like to be
able to have clients on the Ethernet side also mount Lustre. The gateway
extends the same layer-2 IP range that's being used for IPoIB out to the
How should I go about doing this? Since the clients don't have IB, it
doesn't appear that I can use o2ib0 to mount. Do I need to add another
lnet network on the servers? Something like
options lnet networks=o2ib0(ib0),tcp0(ib0)? Can I have both protocols on
the same interface?
And if I do have to add another lnet network, is there any way to do so
without restarting the servers?
