AFAIK, lnet routing doesn't depend on ip_forwarding to work over two tcp networks. BTW, you don't have to explicitly enable lnet forwarding on router nodes. When a node notices that it's used as a router in one of the routes, it will enable forwarding by itself. This gives us a minor administration convenience because the same routing parameters can be used over a whole cluster. In this case, it shall suffice to just specify routes on all nodes as: routes="tcp1 [EMAIL PROTECTED]"; tcp0 [EMAIL PROTECTED]" Hope this helps, Isaac _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
