thank Michael, This is my second step, I will change the lnet with “options lnet networks=tcp0(bond0,bond1)” because my machines has 4 nics. I have a bond0 and bond1 with LACP. I need to comunicate the clients with two network for HA network.
If the bond0 network is down, the clients can reach the OSS by the second network bond1. If I change the modprobe with “options lnet networks=tcp0(bond0),tcp1(bond1)”, how the clients mount the filesystem to reach the OSS by two network?

Of course, that assumes your clients are configured to use a mix of tcp0 and tcp1 for connections (with each client only using one of the two). This is really only useful in corner cases, when you're doing something strange; if eth0 and eth1 are in the same subnet (as in your example), this is almost certainly not productive. A better bet might be to use a single LNET, and bond the two interfaces together - either as an active/passive pair, or active/active (e.g., LACP). Then you'd declare networks=tcp0(bond0), give the bond a single IP address, and client traffic would be split across the two members in the bond more like you probably expect (given the limits of the bond protocol you're using). -- Mike Shuey On Tue, Jun 25, 2013 at 8:06 AM, Alfonso Pardo <alfonso.pa...@ciemat.es> wrote: hello friends, I need to comunicate my OSS by two ethernet TCP interfaces: eth0 and eth1. I have configured this feature in my modprobe.d with: “options lnet networks=tcp0(eth0,eth1)” And I can see two interfaces with: lctl --net tcp interface_list sa-d4-01.ceta-ciemat.es: (192.168.11.15/255.255.255.0) npeer 0 nroute 2 sa-d4-01.ceta-ciemat.es: (192.168.11.35/255.255.255.0) npeer 0 nroute 0 But, the clients only can communicate with the first interface: lctl ping 192.168.11.15 12345-0@lo 12345-192.168.11.15@tcp lctl ping 192.168.11.35 failed to ping 192.168.11.35@tcp: Input/output error Any suggestions how to “enable” the second interface? thank in advance Alfonso Pardo Diaz System Administrator / Researcher c/ Sola nº 1; 10200 TRUJILLO, SPAIN Tel: +34 927 65 93 17 Fax: +34 927 32 32 37 ---------------------------- Confidencialidad: Este mensaje y sus ficheros adjuntos se dirige exclusivamente a su destinatario y puede contener información privilegiada o confidencial.
