Re: [ovirt-users] VM HostedEngie is down. Exist message: internal error Failed to acquire lock error -243

I'm really having a hard time finding out why it's happening.. If I set the cluster to global for a minute or two, the scores will reset back to 2400. Set maintenance mode to none, and all will be fine until a migration occurs. It seems it tries to migrate, fails and sets the score to 0 permanently rather than the 10? minutes mentioned in one of the ovirt slides. When I have two hosts, it's score 0 only when a migration occurs. (Just on the host which doesn't have engine up). The score 0 only happens when it's tried to migrate when I set the host to local maintenance. Migrating the VM from the UI has worked quite a few times, but it's recently started to fail. When I have three hosts, after 5~ mintues of them all up the score will hit 0 on the hosts not running the VMs. It doesn't even have to attempt to migrate before the score goes to 0. Stopping the ha agent on one host, and "resetting" it with the global maintenance method brings it back to the 2 host scenario above. I may move on and just go back to a standalone engine as this is not getting very much luck..
