It seems there is a test_24u and test_24w but no v.</p> <p>Do you have more info you can share? How did you run the test? </p> <p>Here are the debug log and trace from the client. The system actually hung, so I abort the testing.</p> <p>Fan Yong,<br/> Could you please have a look at this one?<br/> Thank you!</p> <p>We shouldn't get a hash collision with just 100k files. I wonder if something bad is happening with the hash mapping in the ZFS code?</p> <p>This is the patch:</p> <p><a href="http://review.whamcloud.com/#change,5894" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#change,5894</a></p> <p>Landed for 2.4</p> Duplicate LU-3119 Related LU-3605 Development Rank 1|hzvlp3: Rank (Obsolete) 7284 Severity
