Are you sure this range is not already included in the <tt>csd3</tt> nodemap?</p> <p>Weirdly, yes, it is showing up when viewing the ranges from this server, which is in a HA pair and is mounting only the MGS currently:</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> [root@rds-mds10 ~]# lctl get_param nodemap.csd3.ranges | grep 10.43.240 { id: 88, start_nid: 10.43.240.198@tcp2, end_nid: 10.43.240.199@tcp2 }, </pre> </div></div> <p>but is <b>not</b> visible from the partner server, currently mounting the MDTs for this filesystem (and was where I was testing this from initially).</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> [root@rds-mds9 ~]# lctl get_param nodemap.csd3.ranges | grep 10.43.240.198</pre> </div></div> <p>and this nodemap has a fileset configured, and the clients whose IPs I'm trying to add here, cannot mount the filesystem.</p> <p>So I guess this is some kind of communication problem with the MGS, possibly related to my other issue mentioned in <a href="https://jira.whamcloud.com/browse/LU-14802" title="MGS configuration problems - cannot add new OST, change parameters, hanging" class="issue-link" data-issue-key="LU-14802"><del>LU-14802</del></a></p> <p>For what it's worth I've tried simply restarting the MGS itself, but that didn't help things. I could try fail it over to the other server, but due to the issues I was having in <a href="https://jira.whamcloud.com/browse/LU-14802" title="MGS configuration problems - cannot add new OST, change parameters, hanging" class="issue-link" data-issue-key="LU-14802"><del>LU-14802</del></a>, I've kept the MGT device on a separate server so it can be restarted without impacting the MDT devices.</p> <p>Thanks for the quick replies,<br/> Matt</p> <p>Let's focus on <a href="https://jira.whamcloud.com/browse/LU-14802" title="MGS configuration problems - cannot add new OST, change parameters, hanging" class="issue-link" data-issue-key="LU-14802"><del>LU-14802</del></a></p> Duplicate LU-14802 Development Rank 1|i01zf3: Rank (Obsolete) 9223372036854775807 Severity
