Question/Request Critical Resolved Incomplete Brian Murrell sebg-crd-pm Tue, 7 Nov 2017 03:53:25 +0000 Tue, 27 Feb 2018 14:24:21 +0000 Tue, 27 Feb 2018 14:24:21 +0000 0 5 <p>Since the Lustre MDS code is running in the kernel, it is possible that the HA threads running on the server can be starved if there is a high load, so the current timeout is not long enough. You might consider to update the token timeout in the <tt>/etc/corosync/corosync.conf</tt> file. </p> <p>Brian</p> <p>Any additional advice to provide here?</p> <p>Peter</p> <p>Is this a Pacemaker configuration that IML constructed or one that you built up yourself?</p> <p>In any case, it looks like your fencing devices are not functioning properly.  It could be a configuration problem or unfortunately just par for the course for IPMI fencing devices.</p> <p>Hi <a href="https://jira.whamcloud.com/secure/ViewProfile.jspa?name=sebg-crd-pm" class="user-hover" rel="sebg-crd-pm">sebg-crd-pm</a>.  Do you have any more information you can add to this ticket or shall I close it?</p> Development Rank 1|hzzn87: Rank (Obsolete) 9223372036854775807
