I configured udev to name the myri10ge interface 'myri10ge'.

I do not think, that myri10ge supports RDMA MX, does it? But my question still is: Why does lctl peer_list shows a connection between MDS and lustre client, which uses the management network, although the client is configured to use myri10ge network only? I recently upgraded to 1.6.5, which has the same result. # On MDS lctl > network tcp0 lctl > peer_list [EMAIL PROTECTED] [0]0.0.0.0->0.0.0.0:0 #0 # On Client 1 lctl > network tcp0 lctl > peer_list [EMAIL PROTECTED] [1]node001-10g->node009-10g:988 #3 Client1 has a correct entry regarding the MDS, while the MDS resolves the source of Client1 incorrectly. This might be a misconfiguration, but I can not figure out where. -- Bastian Tweddell Juelich Supercomputing Centre Institute for Advanced Simulation Forschungszentrum Juelich GmbH 52425 Juelich, Germany Phone: +49-2461-61-6586 Fax: +49-2461-61-6656 WWW: http://www.fz-juelich.de/jsc/ JSC is the coordinator of the John von Neumann Institute for Computing and member of the Gauss Centre for Supercomputing ------------------------------------------------------------------- ------------------------------------------------------------------- Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
