I don't know enough about this area to speculate on severity, but it seems pretty serious to me. The upshot is that changelogs don't make sense with the default jobid_var setting.</p> <p>Please see the attached reproducer script for details.</p> Seen on master as of b6a3222 LU-5862

I haven't started working on a patch. It would probably be faster for you to create one, since you're familiar with the code already. While you're in there, would you also please take a look at <a href="https://jira.whamcloud.com/browse/LU-5859" title="Running lfs changelog with no registered user results in LBUG" class="issue-link" data-issue-key="LU-5859"><del>LU-5859</del></a> to see if it's related? It may not be &#8211; I haven't done a bisect to figure out when that one was introduced. It seems plausible that they could be related, though.</p> <p>James</p> <p>Could you please take care of this patch?</p> <p>Thanks</p> <p>Peter</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/12574/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/12574/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-5862" title="Jobstats tracking in changelogs doesn&#39;t support jobid_var=disable" class="issue-link" data-issue-key="LU-5862"><del>LU-5862</del></a> changelog: Proper record remapping<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: a98690be9057f409b7840dc15c75f28d2c861c92</p> <p>Landed to master (pre-2.7).</p> Related LU-1996 LU-5907 LU-5899 Development Rank 1|hzx06v: Rank (Obsolete) 16403 Severity
