MDS Crash & reboot

Bug Major Resolved Incomplete Zhenyu Xu Fabio Verzelloni Mon, 4 Jun 2012 02:52:31 +0000 Mon, 29 May 2017 03:55:32 +0000 Mon, 29 May 2017 03:55:32 +0000 Lustre 2.2.0 0 2 <p>Bobijam will help with this one</p> <p>from the messages, the system received heartbeat shutdown notice from weisshorn02 node, that maked MDS reboot. Before that </p> <blockquote> <p>May 30 17:36:13 weisshorn02 heartbeat: <span class="error">&#91;3277&#93;</span>: info: Heartbeat shutdown in progress. (3277)<br/> May 30 17:36:14 weisshorn01 heartbeat: <span class="error">&#91;5612&#93;</span>: info: Received shutdown notice from 'weisshorn02.admin.cscs.ch'.</p></blockquote> <p>Can not find the evidence of MDS crash, would you mind collecting MDS debug logs and tell me when did the MDS crash?</p> <p>Also from the log you've uploaded, there are several messages showing that "ldap_result() failed: Can't contact LDAP server", does the network have problem, is it the same network which heartbeat uses?</p> Development Rank 1|hzv3bz: Rank (Obsolete) 4039 Severity
