Bug Major Resolved Fixed Niu Yawei Mahmoud Hanafi mn1 mn4 Tue, 3 Dec 2013 01:01:25 +0000 Fri, 14 Feb 2014 17:04:24 +0000 Fri, 14 Feb 2014 17:04:24 +0000 Lustre 2.4.1 Lustre 2.6.0 Lustre 2.5.1 0 4 <p>1515870810 is 0x5a5a5a5a, which means the oqi in hash has been freed at this moment, looks there is an obvious race between osc_quota_setdq() and osc_quota_chkdq(). I'll cooke a patch to fix it soon.</p> <p><a href="http://review.whamcloud.com/8460" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8460</a></p> <p>Could this be related to Lu-4249. They are both the same filesystem</p> <blockquote> <p>Could this be related to Lu-4249. They are both the same filesystem</p></blockquote> <p>I don't think so, this is a client bug, whereas <a href="https://jira.whamcloud.com/browse/LU-4249" title="exception RIP: lqe64_hash_keycmp+12" class="issue-link" data-issue-key="LU-4249"><del>LU-4249</del></a> is a server side problem, and not like the oqi hash on client, the server side lqe hash has reference count for each lqe, so it has no such race in theory.</p> <p>b2_1: <a href="http://review.whamcloud.com/8596" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8596</a><br/> b2_4: <a href="http://review.whamcloud.com/8595" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8595</a></p> <p>Landed for 2.5.1 and 2.6.
