Ravi, could you please investigate? Since the issue is being caused by zombie tasks, unlocking the entity is not sufficient. The zombie task needs to be cleaned up. Cleaning the zombie task should stop the log messages.
export PGPASSWORD="${ENGINE_DB_PASSWORD}"
cd /usr/share/ovirt-engine/setup/dbutils
./taskcleaner.sh -u "${ENGINE_DB_USER}" -d "${ENGINE_DB_DATABASE}"
./unlock_entity.sh -u "${ENGINE_DB_USER}" -d "${ENGINE_DB_DATABASE}" -t all
I confirm the 'taskcleaner.sh' command along with 'unlock_entity.sh' indeed cleared the hung events and it stopped showing up in the task list. Thanks! |
Created attachment 1210454 [details] ovirt-engine logs Description of problem: We've recently had a problem migrating a few disks from one iSCSI-based datastore to another, as the task seemed stalled after 2 days having in consideration these were small disks, around 30 GB each. (we found nothing relevant in the logs about why did it stall). We found a utility called: unlock_entity.sh, which we used to unblock the tasks from the Events tab: PGPASSWORD=dbpass /usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh -v -u engine -d engine -t disk <disk-uuid> This seemed to work, but now we have lots of events like this in the events list: Clearing asynchronous task Unknown that started at Tue Oct 11 07:46:40 WEST 2016. This message seems to appear in an once per minute interval. This is not a serious issue, but it's very annoying. A restart of the ovirt-engine did not help. I'm attaching ovirt-engine logs.
