Hi, Creating snapshot of one of the VM vailed, and zombie tasks was killed with: su postgres psql -d engine -U postgres select * from job order by start_time desc; select DeleteJob('UUID_FROZEN_TASK_ID’); However, VM remains in locked state (with lock sign left-below red “DOWN” arrow in status column of web interface. I run: /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t all then rebooted engine VM, still no luck. Can’t do anything with that VM. Please advise how to fix. Thanks in advance. _______________________________________________ Users mailing list -- users(a)ovirt.org To unsubscribe send an email to users-leave(a)ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/P2TVMLHC53J...

Hi, Benny, I have sent log on your mailbox, its too big to post here on mailing list. Looks like ghost task is still running, anything else need to be removed from Postgres DB? BTW, frozen dead snapshot is in invalid state, is there any way to get rid of it? I think it's actually exists, but due to invalid state its not possible to do anything with it. —— Log file still shows zombie task: 2022-08-04 20:57:30,145+03 INFO [org.ovirt.engine.core.bll.SerialChildCommandsExecutionCallback] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-24) [28353fa0-5e36-4fe8-8609-e74cd1da6d36] Command 'CreateSnapshotForVm' (id: '2f8b32d8-fd3c-46c9-90e9-4863d63c0530') waiting on child command id: 'ed816f9d-e25c-4b58-8c8f-fd0393abda2f' type:'CreateLiveSnapshotForVm' to complete 2022-08-04 20:57:40,176+03 INFO [org.ovirt.engine.core.bll.SerialChildCommandsExecutionCallback] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-85) [28353fa0-5e36-4fe8-8609-e74cd1da6d36] Command 'CreateSnapshotForVm' (id: '2f8b32d8-fd3c-46c9-90e9-4863d63c0530') waiting on child command id: 'ed816f9d-e25c-4b58-8c8f-fd0393abda2f' type:'CreateLiveSnapshotForVm' to complete 2022-08-04 20:57:50,252+03 INFO [org.ovirt.engine.core.bll.SerialChildCommandsExecutionCallback] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-66) [28353fa0-5e36-4fe8-8609-e74cd1da6d36] Command 'CreateSnapshotForVm' (id: '2f8b32d8-fd3c-46c9-90e9-4863d63c0530') waiting on child command id: 'ed816f9d-e25c-4b58-8c8f-fd0393abda2f' type:'CreateLiveSnapshotForVm' to complete > On 4 Aug 2022, at 19:06, Benny Zlotnik <bzlotnik(a)redhat.com&gt; wrote: > > can you share the logs after restarting ovirt-engine? > > On Thu, Aug 4, 2022 at 4:58 PM Andrei Verovski <andreil1(a)starlett.lv&gt; wrote: >> >> Hi, >> >> >> Creating snapshot of one of the VM vailed, and zombie tasks was killed with: >> >> su postgres >> psql -d engine -U postgres >> select * from job order by start_time desc; >> >> select DeleteJob('UUID_FROZEN_TASK_ID’); >> >> >> However, VM remains in locked state (with lock sign left-below red “DOWN” arrow in status column of web interface. >> >> I run: >> /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -t all >> >> then rebooted engine VM, still no luck.

I made clone from one of them ant the clone works properly.
