[ACTION REQUIRED] Dropping oVirt 4.1 in CI
by Ehud Yonasi 29 Jul '18

29 Jul '18

Hey everyone, Since oVirt 4.1 has gone EOL, it is time to drop all related jobs in CI which includes: - All 4.1 jobs related - All 4.1 change queue jobs - The 'tested' repository under resources - The 4.1 nightly snapshot repository jobs Maintainers, if your projects have any dependencies on the resources above, please be sure to update them to more up to date or stable resources. In particular, to depend on any 4.1 packages, please use the 4.1 released repo at: Thanks in advance for your cooperation, Ehud.

[ATT] OST 'master' is now broken because of a change in CentOS - DEVELOPMENT BLOCKED
by Barak Korren 29 Jul '18

29 Jul '18

The openstack-java-glance-* packages in CentOS have been updated in a way that is now incompatible with how engine had been using Glance. This in turn causes any OST run to break ATM, which means no patches are currently making it past OST and CQ and into the 'tested' and nightly snapshot repositories. So far we've only seen this affect 'master' but since the change was made in CentOS, there is no reason to believe it will not break other version as well. A fix to engine to make it compatible with the new package had been posted here: https://gerrit.ovirt.org/c/93352/ Additionally, an issue in OST had made this harder to diagnose then it should have been, and was fixed here: https://gerrit.ovirt.org/c/93350/ Actions required: 1. Please avoid merging any unrelated patches until the issue is fixed 2. If you've merged any patches since Friday morning, please not that there were probably removed from the change queue asfailed changes, ad willl need to be resubmitted by either merging a newer patch to the relevant project, commenting "ci re-merge please" on the latest merged patch in Gerrit or resenting the Webhook event from GitHub. 3. If you can please help with reviewing, merging and back-porting the patches above to speed up resolution of this issue. Here is a list of project for which we've seen patches get dropped over the weekend - ovirt-provider-ovn - ovirt-engine - ovirt-ansible-vm-infra - vdsm Tracker ticket for this issue: https://ovirt-jira.atlassian.net/browse/OVIRT-2375 -- Barak Korren RHV DevOps team , RHCE, RHCi Red Hat EMEA redhat.com | TRIED.

[ OST Failure Report ] [ oVirt Master (ALL) ] [ 27-07-2018 ] [ 002_bootstrap.list_glance_images ]
by Dafna Ron 27 Jul '18

27 Jul '18

Hi, We seem to have a problem in the OST tests that is causing failure in multiple projects The issue is that setting __name__ on local function is not working correctly and we are exiting instead of skipping when Glance image is not available. We had the same issue on a different test where Milan fixed it: https://gerrit.ovirt.org/#/c/93167/ but now it seems that we have the same issue on list_glace_images as well. ERROR: Traceback (most recent call last): File "/usr/lib64/python2.7/unittest/case.py", line 369, in run testMethod() File "/usr/lib/python2.7/site-packages/nose/case.py", line 197, in runTest self.test(*self.arg) File "/usr/lib/python2.7/site-packages/ovirtlago/testlib.py", line 129, in wrapped_test test() File "/usr/lib/python2.7/site-packages/ovirtlago/testlib.py", line 59, in wrapper return func(get_test_prefix(), *args, **kwargs) File "/usr/lib/python2.7/site-packages/ovirtlago/testlib.py", line 78, in wrapper prefix.virt_env.engine_vm().get_api(api_ver=4), *args, **kwargs File "/home/jenkins/workspace/ovirt-master_change-queue-tester/ovirt-system-tests/basic-suite-master/test-scenarios/002_bootstrap.py", line 633, in list_glance_images raise SkipTest('%s: GLANCE connectivity test failed' % list_glance_images_4.__name__ ) NameError: global name 'list_glance_images_4' is not defined

storage domain deactivating
by Hetz Ben Hamo 26 Jul '18

26 Jul '18

Hi, As part of my "torture testing" to oVirt (4.2.4) I'm doing some testing with 1 node where I shut down the HE and the machine (powering off, not yanking the power cable) and rebooting to see it's survival status. One of the weird thing that happens is that when the machine boots and it starts the HE, it mounts the storage domains and everything works. However, after few moments, 3 of my 4 storage domains (ISO, export, and another storage domain, but not the hosted_engine storage domain) is being automatically deactivted, with the following errors: VDSM command GetFileStatsVDS failed: Storage domain does not exist: (u'f241db01-2282-4204-8fe0-e27e36b3a909',) Refresh image list failed for domain(s): ISO (ISO file type). Please check domain activity. Storage Domain ISO (Data Center HetzLabs) was deactivated by system because it's not visible by any of the hosts. Storage Domain data-NAS3 (Data Center HetzLabs) was deactivated by system because it's not visible by any of the hosts. Storage Domain export (Data Center HetzLabs) was deactivated by system because it's not visible by any of the hosts. However, when I see those message and I'm manually re-activating those storage domains, all of them getting the status "UP" and there are no errors and I can see disks, images, etc... Should I open a bug in Bugzilla about this issue? Thanks

OST: Cluster compatibility testing
by Milan Zamazal 26 Jul '18

26 Jul '18

Hi, CI runs now OST basic-suite-master periodically with data center and cluster versions different from the default one on master. That tests changes in master for breakages when run in older version compatibility modes. Contingent failures are reported to infra. If you make an OST test known not to run on older cluster versions (e.g. < 4.1), you should mark the test with a decorator such as @versioning.require_version(4, 1) You can also distinguish cluster version dependent code inside tests by calling versioning.cluster_version_ok(4, 1) See examples in basic-suite-master. You can run basic-suite-master with a different data center and cluster version manually on your computer by setting OST_DC_VERSION environment variable, e.g.: export OST_DC_VERSION=4.1 ./run_suite.sh basic-suite-master Barak, it's currently possible to request OST run on Gerrit patches. I was asked whether it is also possible to request an OST run with a non-default cluster version(s). Is it or not? Thanks, Milan

May snapshot status be `OK' before snapshot creation finishes?
by Milan Zamazal 26 Jul '18

26 Jul '18

Hi, a failure of previewing a snapshot with memory has been experienced in OST master suite and I'm not sure whether REST API responses about snapshot status are correct or not. When I'm creating a snapshot with memory, <snapshot_status> reported from Engine REST API in /api/vms/…/snapshots is initially `locked' and later switches to `ok'. The problem is that `ok' starts being reported before snapshot creation completes, resulting in errors if I try to stop the VM or to preview the snapshot at the moment. Does <snapshot_status>ok</snapshot_status> guarantee that the snapshot is completed or not? I can see the following example in ovirt-engine-sdk (for snapshot without memory): # 'Waiting for Snapshot creation to finish' snapshot_service = snapshots_service.snapshot_service(snapshot.id) while True: time.sleep(5) snapshot = snapshot_service.get() if snapshot.snapshot_status == types.SnapshotStatus.OK: break So I suppose snapshot status shouldn't switch to OK before snapshot creation finishes. But it's not true in Engine master. Is it a bug or a feature? Thanks, Milan
