Despite there is no logs about changing edquot from 1 to 0(somehow there is nothing about that and I believe this part of logs missed), I think as was written only 17MB, not 20, OSTs could send release requests causing to change edquot flag from 1 to 0. Thus when it writes the rest 2MB(there are 2 OSTs) it doesn't fail as there is no EDQUOT flag anymore and finally it writes just 19(17+2) MB instead of 22(20+2).</p> <p>"Sergey Cheremencev &lt;scherementsev@ddn.com&gt;" uploaded a new patch: <a href="https://review.whamcloud.com/c/fs/lustre-release/+/53038" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/c/fs/lustre-release/+/53038</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-17046" title="sanity-quota test_1g: user write success, but expect EDQUOT" class="issue-link" data-issue-key="LU-17046"><del>LU-17046</del></a> tests: fix write success in 1g<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 072e51154c13e7abf035a75018e52dc94c04806c</p> <p>There is a lot of failures of sanity-quota_1g last time.
