Hi,

We have a single cluster with 6 Nodes in a single DC and added 4 FC 
Storage domains. All the while it was working fine, migrations, creation 
of new VMs everything were working fine. Now, all of a sudden we see the 
error message "vdsm is unable to communicate with Master domain ......." 
and all storage domains, including DC are down. But all Hosts are up, 
all VMs are running without any issues. But migrations stopped, we 
cannot create new VMs, we cannot start a shutdown VM.

Can someone help us trouble shoot the issue?

By the way, we are running oVirt Version 4.0.1.
