when you login to the storage you need to set max_sect to something other than the default of 512 (blocks). try 1024 or 2048. then use sg_dd's direct i/o mode (dio=1) or dd with iflag=direct/oflag=direct). you should be able to bigger rdma segments that way. _______________________________________________ general mailing list [email protected] http://lists.openfabrics.org/cgi-bin/mailman/listinfo/general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
