[Lustre-discuss] lustre performance degrade on SuSE 11

[Tharindu Rukshan Bamunuarachchi]

hi All,

 

I have following lustre installation.

 

Node A : OSS (SuSE 10) - 1.8.0

Node B : MDS (SuSE 10) - 1.8.0

 

Node C: Client (SuSE 11) - 1.8.1

 

When try to run "dd" command on lustre mount, it is only writing at 2.1 MB/s

But If mount same file system on Node B, I can achive 45 MB/s performance.

 

All nodes are connected to same 3560G cisco switch.

 

I saw following error in MDS server message file. Is this related to
performance of lustre file system ?

 

LustreError: 3039:0:(socklnd_cb.c:2228:ksocknal_recv_hello()) Unknown
protocol version (2.x expected) from 172.25.88.202

 

 

cheers,
