You can do this, simply define networks for both devices. Assuming ib0, and eth0, you would have options lnet networks="tcp0(eth0),o2ib0(ib0)"
The IB clients will mount using a @o2ib0 NID, and the ethernet clients will mount using @tcp0 NIDs. Since you are explicitly specifying the network, the hop rule doesn't apply. cliffw On Fri, Dec 16, 2011 at 9:49 AM, Patrice Hamelin <patrice.hame...@ec.gc.ca>wrote: > ** > Hi, > > I have two Infiniband clusters, each in a separate location with a solid > ethernet connectivity between each of them.
