Because it relies on the update log, which regular FID file, mapped through OI. i.e. after MDT backup and restore, recovery thread will not be able to retrieve the update log file correctly, because OI scrub is not running until recovery finished. </p> <p>So we probably should let OI scrub fix some key file first like update log, then start recovery. </p> LU-6380

OI scrub should be able to scan the update log file before replay

Bug Blocker Resolved Fixed nasf Di Wang dne2 Wed, 18 Mar 2015 17:10:36 +0000 Fri, 9 Sep 2016 20:14:13 +0000 Sat, 4 Jul 2015 01:56:53 +0000 Lustre 2.8.0 Lustre 2.8.0 0 4 <p>Currently, the initial OI scrub will fix some key files before recovery, such as ROOT, .lustre, and so on. These files either have known FID or not care about what the FID is. As for the update log, it is new for DNE2, we can make the initial OI scrub to handle them before recovery. But because the update log's FID is stored as its name, then the initial OI scrub needs to handle them specially.</p> <p>Please also include a test for OI Scrub rebuilding OI files for an MDT in recovery.</p> <p>Fan Yong (fan.yong@intel.com) uploaded a new patch: <a href="http://review.whamcloud.com/15192" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/15192</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6380" title="OI scrub should be able to scan the update log file before replay" class="issue-link" data-issue-key="LU-6380"><del>LU-6380</del></a> scrub: handle update_log during initial scrub<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 6c50004f61c95241fa5f026e540e3172589f06ba</p> <p>Oleg Drokin (oleg.drokin@intel.com) merged in patch <a href="http://review.whamcloud.com/15192/" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/15192/</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-6380" title="OI scrub should be able to scan the update log file before replay" class="issue-link" data-issue-key="LU-6380"><del>LU-6380</del></a> scrub: handle update_log during initial scrub<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: <br/> Commit: 342149e654cdde71b34ad0148749adc7cf9f7cfe</p> <p>The patch has been landed to master.</p> Related LU-3534 Development Rank 1|hzx8tz: Rank (Obsolete) 9223372036854775807 Severity
