<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Hi, all.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Currently, I have some problem with Lnet bonding configuration.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">First of all, my server configuration is as below :</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">1 server and 1 client</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Lustre version - 2.15.3.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">MGT, 1 MDT and 1 OST have on same server. </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Bonding with 2 Infiniband interfaces ( ib0, ib1 ).</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Client also configure bonding with Infiniband.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">And, my problem scenario is as below :</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Under those configurations, I mounted lustre on client and run benchmarks.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Then, I plugged out ib0 cable from the server.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">After that, client I/O was pending 20~40 seconds.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">I think that It takes too long. </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">So, does anyone who has same experience with same configurations?</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">I wondering that It usually takes that time.</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">If it's not normal, what's the problem?</p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt"> </p>
<p style="margin:0px; font-family:\ub9d1\uc740 \uace0\ub515; font-size:10pt">Best regards,</p>
