Re: CI slaves extremely slow - overloaded slaves?

Hi all, In the last weeks we see more and more test failures due to timeouts in the CI. For example: 17:19:49 ====================================================================== 17:19:49 FAIL: test_scale (storage_filesd_test.GetAllVolumesTests) 17:19:49 ---------------------------------------------------------------------- 17:19:49 Traceback (most recent call last): 17:19:49 File "/home/jenkins/workspace/vdsm_master_check-patch-fc24-x86_64/vdsm/tests/storage_filesd_test.py", line 165, in test_scale 17:19:49 self.assertTrue(elapsed < 1.0, "Elapsed time: %f seconds" % elapsed) 17:19:49 AssertionError: Elapsed time: 1.105877 seconds 17:19:49 -------------------- >> begin captured stdout << --------------------- 17:19:49 1.105877 seconds This test runs in 0.048 seconds on my laptop: $ ./run_tests_local.sh storage_filesd_test.py -s nose.config: INFO: Ignoring files matching ['^\\.', '^_', '^setup\\.py$'] storage_filesd_test.GetAllVolumesTests test_no_templates OK test_no_volumes OK test_scale 0.047932 seconds OK test_with_template OK ---------------------------------------------------------------------- Ran 4 tests in 0.189s It seems that we are overloading the CI slaves. We should not use nested kvm for the CI, such vms are much slower then regular vms, and we probably run too many vms per cpu. We can disable such tests in the CI, but we do want to know when there is a regression in this code. Before it was fixed, the same test took 9 seconds on my laptop. We need fast machines in the CI for this. Nir _______________________________________________ Infra mailing list Infra(a)ovirt.org http://lists.ovirt.org/mailman/listinfo/infra
