sanity test_101a: too many discarded pages

Bug Minor Resolved Fixed Patrick Farrell Maloo Thu, 28 Nov 2013 03:05:53 +0000 Thu, 9 Jan 2020 07:38:56 +0000 Fri, 4 Oct 2019 13:23:14 +0000 Lustre 2.6.0 Lustre 2.13.0 0 9 <p>Hmm, I do not know why this only happens in DNE, since it is nothing different compared single MDT run. The only reason here, might be in DNE it use 2 OSS (4 OSTs each OSS), in single MDT, it use single OSS with 8 OSTs. I do not know why we only use 1 OSS in single MDT test. </p> <p>And also discarded pages might be related with memory pressure, but I did not figure out the real reason yet. For now, I will disable this test for DNE.</p> <p><a href="http://review.whamcloud.com/8428" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/8428</a></p> <p>Patch landed to Master.</p> <p>The patch was landed to disable sanity.sh test_101a, but the problem was never actually fixed.
