Bug Minor Resolved Cannot Reproduce Lai Siyao Maloo Mon, 10 Oct 2011 22:04:13 +0000 Mon, 29 May 2017 02:42:33 +0000 Mon, 29 May 2017 02:42:33 +0000 Lustre 2.3.0 0 5 <p>Another similar failure instance, "rcmd: xpoll: protocol failure in circuit setup". I am not sure what happened.</p> <p><a href="https://maloo.whamcloud.com/test_sets/7b1c412a-0803-11e1-b0d9-52540025f9af" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/7b1c412a-0803-11e1-b0d9-52540025f9af</a></p> <p>Another similar failure <a href="https://maloo.whamcloud.com/test_sets/14900348-8827-11e1-8e21-525400d2bfa6" class="external-link" target="_blank" rel="nofollow noopener">https://maloo.whamcloud.com/test_sets/14900348-8827-11e1-8e21-525400d2bfa6</a> .</p> <p>Hi Lai</p> <p>Could you please look into this one?</p> <p>Thanks</p> <p>Peter</p> <p>Are these tests run as root? The message "protocol failure in circuit setup" from rcmd indicates that one of two things have happened: 1- rcmd is trying to use a port number less than 1024 and does not have root privileges (need root to access port numbers less than 1024), 2- the other end has refused the connection (too busy?).</p> <p>Generally such failure is triggered by pdsh command, and the maloo logs show the failed command are executed as root, so the second one might be the possible cause, but this is hard to identify. I haven't seen such failure for a while, if we can find a way to reproduce this failure, it will be easier to find the cause.</p> <p>Not failing very often if at all anymore so dropping priority</p> <p>Close old ticket.</p> Related Development Rank 1|hzvayn: Rank (Obsolete) 5312 Severity
