Hi, we have two clusters (let's call them A and B); each with a "local" Infiniband network and a Lustre filesystem. Both clusters can see each other via GBit Ethernet but not via Infiniband.
We'd now like to mount Lustre-A on the login node A via Infiniband (o2ib) but in addition also Lustre-B via GBit Ethernet (eth0). (And vice versa on the login node of B.) However, even if the initial connect of login-A to Lustre-B is initiated via eth-NID it gets the IB-NID back from the MDS and subsequently tries to reach the MDS/OSS via Infiniband; but there is no physical connection between the two Infiniband networks. Any ideas/suggestions? Except also accessing Lustre-A from login-A only via GBit Ethernet, i.e. loading lnet without support for o2ib.
