You can run this on the host: vdsClient -s 0 getAllTasksStatuses And share the output. > What can i do for resolve the problem? You should see the status of each task - if you have a finished task, and engine is not clearing it, this is a bug in engine - please file a bug and attached vdsm and engine logs. To clear the a finished task not cleared by the engine, try to restart the engine. If engine is not clearing finished tasks after restart, you can clear it yourself: vdsClient -s 0 clearTask <task uuid> Nir > Thanks in advance > > Nicola > _______________________________________________ > Users mailing list > Users(a)ovirt.org > http://lists.ovirt.org/mailman/listinfo/users
