[ovirt-devel] OST fails in verify_backup_snapshot_removed

Hi all, OST manual job failed for me a few times recently in 004_basic_sanity.verify_backup_snapshot_removed , last two (both with what I think are unrelated changes) are: 1. https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-te... with the copyright notices patches to the engine: https://gerrit.ovirt.org/97698 2. https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-te... with the unicode patches to the engine and to otopi: https://gerrit.ovirt.org/102936 https://gerrit.ovirt.org/102938 In job console, you can see that remove_backup_vm_and_backup_snapshot finished successfully, and several minutes latee verify_backup_snapshot_removed fails with a timeout. In between, engine.log has several ERRORs, e.g.: https://jenkins.ovirt.org/view/oVirt%20system%20tests/job/ovirt-system-te... 2019-09-04 11:05:31,271-04 ERROR [org.ovirt.engine.core.bll.storage.disk.image.DestroyImageCommand] (EE-ManagedThreadFactory-engine-Thread-354) [e55e5d43-c168-42b4-9b80-e0cd2b8405bb] Ending command 'org.ovirt.engine.core.bll.storage.disk.image.DestroyImageCommand' with failure. No idea if that's related, didn't dig deeper. Any clue? Is this a known issue? Thanks and best regards, -- Didi
