Is it possible to track it down to a patch that landed in the last couple of days?</p> <p>Lots of the failures are on the two patches:<br/> <a href="http://review.whamcloud.com/10620" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10620</a> <a href="https://jira.whamcloud.com/browse/LU-5150" title="NULL pointer dereference in posix_acl_valid() under mdc_get_lustre_md()" class="issue-link" data-issue-key="LU-5150"><del>LU-5150</del></a> mdc: Handle empty but non-zero acl xattr<br/> <a href="http://review.whamcloud.com/10741" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10741</a> <a href="https://jira.whamcloud.com/browse/LU-5221" title="Missed up_read on mmap_sem in vvp_mmap_locks" class="issue-link" data-issue-key="LU-5221"><del>LU-5221</del></a> vvp: release mmap_sem in error case</p> <p>which puts the likely candidate as:<br/> <a href="http://review.whamcloud.com/10237" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10237</a> <a href="https://jira.whamcloud.com/browse/LU-5164" title="Limit lu_object cache (ZFS and osd-zfs)" class="issue-link" data-issue-key="LU-5164"><del>LU-5164</del></a> osd: Limit lu_object cache</p> <p>This is reinforced by the fact that the first version of the <a href="http://review.whamcloud.com/10237" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10237</a> patch also failed sanity.sh once before it was landed (the only such failure in the past year). The second version of the patch did not fail so it wasn't noticed before landing.</p> <p>One suggestion would be to leave the limiting code in place but simply increase LU_CACHE_NR_ZFS_LIMIT. In practice we haven't seen any issue caused by setting it to 256 but perhaps an Andreas suggested earlier it needs to be at least a large as the number of service threads.</p> <p>Speculative patch:<br/> <a href="http://review.whamcloud.com/10802" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10802</a></p> <p>I've also submitted <a href="http://review.whamcloud.com/10855" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/10855</a> to revert the original 10237 patch as a fallback measure in case 10802 doesn't solve the problem.</p> <p>Another failure instance:<br/> <a href="https://testing.hpdd.intel.com/test_sets/06ab90ae-fd54-11e3-a270-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/06ab90ae-fd54-11e3-a270-5254006e85c2</a></p> <p>Another failure instance:</p> <p><a href="https://testing.hpdd.intel.com/sub_tests/34c145f8-ff87-11e3-af4b-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/sub_tests/34c145f8-ff87-11e3-af4b-5254006e85c2</a></p> <p>Patch landed to Master.</p> <p>Here is the back-ported patch for Lustre b2_5 branch: <a href="http://review.whamcloud.com/12002" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/12002</a></p> Related LU-5164 Development Rank 1|hzwpmv: Rank (Obsolete) 14612 Severity
