I recall we disabled it right before the 2.11 release, but then a patch was landed for 2.12 that fixed the feature and added the test, but it didn't enable the feature again.</p> <p>Well, as my first patch that had landed for this feature (for <a href="https://jira.whamcloud.com/browse/LU-7340" title="ChangeLogs catalog full condition should be handled more gracefully" class="issue-link" data-issue-key="LU-7340"><del>LU-7340</del></a>) had to be reverted by John because of MDT hangs it generated (in <a href="https://jira.whamcloud.com/browse/LU-10680" title="MDT becoming unresponsive in 2.10.3" class="issue-link" data-issue-key="LU-10680"><del>LU-10680</del></a>), seems that at the time I finally pushed the final fix to finalize the feature I was reluctant to enable it by default, this clearly appears in my Commit-message for the patch ("Also, enable Changelog GC, as it is no longer the default, in sanity/test_160f sub-test ...").<br/> And sorry, but I should have made it more clear in <a href="https://jira.whamcloud.com/browse/LU-10680" title="MDT becoming unresponsive in 2.10.3" class="issue-link" data-issue-key="LU-10680"><del>LU-10680</del></a> at this time...</p> <p>Oleg Drokin (green@whamcloud.com) merged in patch <a href="https://review.whamcloud.com/36467/" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36467/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12871" title="enable changelog garbage collection by default" class="issue-link" data-issue-key="LU-12871"><del>LU-12871</del></a> mdd: enable Changelog garbage collection<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 1cc689723685a564c4d3f45ba44348e2e43a8442</p> <p>Landed for 2.14</p> Related LU-10680 LU-7340 LU-12865 LU-14699 LU-17290 Development Rank 1|i00o67: Rank (Obsolete) 9223372036854775807
