lost compute node

I've lost a compute node. For some reason I was in the understanding that my servers would restart on another computer node. But they are stuck in my node and I fail to see how I would start them on another node.

nova list --host os-compute03

I've taken out stuff that I dont care.

I've already rebuilt a new domain controller, so I guess I dont care about ws2k8r2_dc anymore.

I've manage ny editing the INSTACE table in the NOVA database to move a server to another node, but he is so not starting : 9eb3bd5a-2b81-4f5d-83df-74ee56d1b8fe | SVR-ZABBIX | SHUTOFF | - | NOSTATE | vlan15=10.53.220.21

I've played a lot with with the reset state.

I mean, how can I stabilized my cluster without the 3rd cluster member.
