[ovirt-users] Re: how kill backup operation

Thanks Arik, we have tried your solution but with no successful results. we have gather also other infor and combined in this solution: we have deleted on DB the row on vm_backups and vm_disk_map related to the hanged backup. The we have tried to delete shapshot locked , after the row db deletion the messange "cannot delete shapshot during backup operations" does not apper" but deletion failed anyway. so we watch the log file /var/log/ovirt-engine/engine.log ans see this messages nIs another process using the image [ /rhev/data-center/mnt/glusterSD/localhost:_gv0/60b7f172-08ed-4a22-8414-31fd5b100d72/images/5d18a058-652f-4c94-a9ff-9c15152c61b4/f17c3443-b62f-43f5-b35c-5ba9225abaf4 then we search on the node which process olds the file with the command: lsof | grep f17c3443-b62f-43f5-b35c-5ba9225abaf4 and we found on a node that the file was in use by a process qemu-ndb we kill that process and finally we were enabled to delete the shapshot. Thanks again for your support
