What's the lnet module parameters in your modprobe.conf? If you haven't specified any, please read a bit on lnet first: http://manual.lustre.org/manual/LustreManual16_HTML/DynamicHTML-02-1.html http://manual.lustre.org/manual/LustreManual16_HTML/DynamicHTML-05-1.html The Lustre Networking White Paper is also a good read: http://www.clusterfs.com/images/Docs/lustrenetworking_whitepaper_v4.pdf Hope this helps, Isaac _______________________________________________ Lustre-discuss mailing list [email protected] https://mail.clusterfs.com/mailman/listinfo/lustre-discuss
