It also may be the same as <a href="https://jira.whamcloud.com/browse/LU-9247" title="replay-ost-single test_5: test failed to respond and timed out" class="issue-link" data-issue-key="LU-9247"><del>LU-9247</del></a>.</p> <p>Thanks.<br/> Joe</p> <p>migration on ZFS should be very very small as it (migration) involves synchronous I/O which is extremely slow on ZFS w/o ZIL.<br/> I'd suggest to disable this test with ZFS.</p> <p>Thanks Alex, that direction is very helpful. Do you think the same case is true for <a href="https://jira.whamcloud.com/browse/LU-9247" title="replay-ost-single test_5: test failed to respond and timed out" class="issue-link" data-issue-key="LU-9247"><del>LU-9247</del></a>?</p> <p>sanity 230d has timed out three times this year only when running with ZFS and DNE. This testing is done for tagged builds of master.</p> <p>This is only happening with DNE, do we still think that this is just ZFS slowness?</p> <p>For 2017, here are the only cases where 230d times out:<br/> 2.9.52 - <a href="https://testing.hpdd.intel.com/test_sets/f4f9d750-efe8-11e6-8c0d-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/f4f9d750-efe8-11e6-8c0d-5254006e85c2</a><br/> 2.9.54 - <a href="https://testing.hpdd.intel.com/test_sets/6e01cc88-0c1e-11e7-8c9f-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/6e01cc88-0c1e-11e7-8c9f-5254006e85c2</a><br/> 2.9.55 - <a href="https://testing.hpdd.intel.com/test_sets/c4a941a4-1e09-11e7-b742-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/c4a941a4-1e09-11e7-b742-5254006e85c2</a></p> <p>another one on DNE+ZFS 2.9.58</p> <p><a href="https://testing.hpdd.intel.com/test_sets/3b4e3b94-44b5-11e7-b3fe-5254006e85c2" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/3b4e3b94-44b5-11e7-b3fe-5254006e85c2</a></p> <p>Another:<br/> <a href="https://testing.hpdd.intel.com/test_sessions/004b644b-af97-429d-954c-65316b8f7a96" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sessions/004b644b-af97-429d-954c-65316b8f7a96</a></p> <p>+1<br/> <a href="https://testing.hpdd.intel.com/test_sets/8d897e16-0f33-11e8-a6ad-52540065bddc" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/8d897e16-0f33-11e8-a6ad-52540065bddc</a></p> <p>another on b2_10:<br/> <a href="https://testing.hpdd.intel.com/test_sets/0db2bb16-5f93-11e8-b303-52540065bddc" class="external-link" target="_blank" rel="nofollow noopener">https://testing.hpdd.intel.com/test_sets/0db2bb16-5f93-11e8-b303-52540065bddc</a></p> <p>Close as a duplicate of <a href="https://jira.whamcloud.com/browse/LU-11235" title="sanity: test_230d timeout on ZFS backends" class="issue-link" data-issue-key="LU-11235">LU-11235</a>.</p> Duplicate LU-11235 Related LU-9247 Development Rank 1|hzynzr: Rank (Obsolete) 9223372036854775807 Severity
