Brian. Thanks for getting back to me. Yes. The contents matched but getting the RX drop which is king of scary. I am using the same machine when doing the test.
I have already looked at the Lnet tests http://manual.lustre.org/manual/LustreManual16_HTML/LustreIOKit.html#50642990_pgfId-1290255 For some reason, "lst add_group servers ipaddrs_of_OSS_and_MDS" gets me a RPC error but it seems my 5 servers get added. Wierd. Is there better documentation or perhaps an example for the lnet tests I am curious to try it. BTW, I am very happy to see this http://manual.lustre.org/manual/LustreManual16_HTML/LustreTuning.html#50642992_24952 (Last section regarding CRC). Where can I read more about this?? Keep in mind, I am using e1000 NICs, and I think there is some tuning I should be doing (but I am not certain if I am doing the right tuning) TIA On Fri, Nov 14, 2008 at 7:11 AM, Brian J.
