I have a three node Server 2012 cluster with Hyper-V running on the cluster. When I pause a server, and then restart it, I am getting Event ID 1135:
Cluster node 'COTTONMILL' was removed from the active failover cluster membership. The Cluster service on this node may have stopped. This could also be due to the node having lost communication with other active nodes in the failover cluster. Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapters on this node. Also check for failures in any other network components to which the node is connected such as hubs, switches, or bridges.
and also Event ID 1177:
The Cluster service is shutting down because quorum was lost. This could be due to the loss of network connectivity between some or all nodes in the cluster, or a failover of the witness disk.
Run the Validate a Configuration wizard to check your network configuration. If the condition persists, check for hardware or software errors related to the network adapter. Also check for failures in any other network components to which the node is connected
such as hubs, switches, or bridges.
All of my virtual servers stay up though.
Quorum is set at NodeMajority with no witness.
Should I be getting these errors when I pause one node to do maintenance and the other two nodes are running? Thanks.
