And some ELC logic is implemented in lmv layer. A simple way to fix it is to regenerate config logs, please refer to <a href="http://wiki.lustre.org/manual/LustreManual18_HTML/ConfiguringLustre.html" class="external-link" target="_blank" rel="nofollow noopener">http://wiki.lustre.org/manual/LustreManual18_HTML/ConfiguringLustre.html</a> 4.3.11.</p> <p>If this works, do you think it's acceptable. IIRC, regenerating config logs is a common way to fix config issues in upgrade, is it?</p> <p>Hi Lai,<br/> Thanks for the explanation. Next time I perform 1.8-&gt;2.x upgrading testing, I'll regenerate config logs to run sanity test 120*. For the testing without regenerating config logs, I'll skip sanity test 120*.</p> <p>Haven't seen this in a long time.</p> Related LU-4909 Bugzilla ID 23338.0 Development Rank 1|hzv58v: Rank (Obsolete) 4383 Severity
