Hi there, currently our vms are in a non responsive state. Due fibre channel storage problems every machine is tagged by a question mark. Datacenter is in non operational mode. Good news is that the machines are running. I verrified by „virsh list“ on the hypervisors. I know if I reboot the hypervisors then the problem will be solved. But is there any other way to connect the hypervisor hosts to the datacenter? Now storage problems are over and I already tried to restart the vdsm daemon … but no success. Do I really need to reboot the hosts? OS Version of ovirt Hosts: Centos7 DataCenter runs with version 3.5 With best regards Andreas
