It isn't clear if the missing space is a "leak" or if that just represents some internal ZFS data structure that is now being allocated that didn't previously exist and is normal behaviour? The sizes reported in test failures is usually the same (<tt>309264KB - 307632KB = 1632KB</tt>, but there was one failure (of 10 so far) that reported <tt>35840KB - 32768KB = 3072KB</tt>.</p> <p>One way to determine if this is a leak or not would be to run <tt>runtests</tt> several times in a row on the same filesystem, and see if each one is reporting a leak, or if that is only seen on the first one run? It appears that <tt>runtests</tt> is the first test run after the filesystem is formatted, so it may be that there is some space allocated when the filesystem is first used.</p> <p>James Nunez (jnunez@whamcloud.com) uploaded a new patch: <a href="https://review.whamcloud.com/36011" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/36011</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-12579" title="runtests: test_1: @@@@@@ FAIL: Space not all freed: now 309264kB, was 307632kB." class="issue-link" data-issue-key="LU-12579"><del>LU-12579</del></a> tests: check runtests for space leaks<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: 29c4d1629f5b0fef4ac0e142cc3c2666deacaa6b</p> <p>Talking to Behlendorf he suspects its the addition of project quotas to ZFS for the 0.8.1 version.
