Network bridge and clustering functionality with Hyper-V

Posted on 2014-07-15
Last Modified: 2014-11-12
I am currently running a Hyper-V 2012 clustering and when I bridge two of our network adapters I get a warning stating:

"Clustering Services have been detected on this node. Certain clustering functionality may be impaired by the Network Bridge".

Does anyone know what functionality may be impaired?  I hate these vague references and I can't find any MS articles about it.

There is a reason why I am bridging adapters instead of using teaming or NLB so please only post answers that directly relate to clustering functionality impairment please.

    Hi convergint,

    This is because of the CSV (Cluster shared volumes) functionality. The requirements for CSV are explained in this article. It also states: "IP subnet configuration. For each network in a failover cluster where Cluster Shared Volumes is enabled, all nodes must be on the same logical subnet, which means that multisite clusters that use Cluster Shared Volumes must use a VLAN."

    Configuring a network bridge will bind multiple networks together. This is not recommended when using the CSV functionality.
