Hi, I have one interesting issue. I was asked by colleague to repair his cluster which is part of our oVirt installation. He tried to upgrade his host to gain 4.2 compatibility level but it fails in some cases. Never mind, I checked it, repaired, installed upgrades and activate his hosts with one exception. One of hosts was stucked in finishing two tasks. One was changing network configuration, the second was activating of this host. I have to manually clear this tasks in database by SELECT * FROM job ORDER BY start_time DESC; SELECT DeleteJob('...job_id...'); SELECT DeleteJob('...job_id...'); Now this tasks are gone but still cannot activate this host. Error while executing action: blade01: Cannot activate Host. Related operation is currently in progress. Please try again later. Host is updatet (latest 4.2 repo), rebooted, looks fine... In tasks in UI are no tasks found (the same in db)... What can I do now? Cheers, Jiri
