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 Ethernet clients 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?
