Hi,
we have a 4 node Hyper-V Server 2008 R2 SP1 Cluster with a few VMs. Since this week on monday we have problems while accessing CSVs from some nodes.
NodeNames:
130
131
132
133
For example: If Node 133 owns all three CSVs everything is working fine.
If I transfer the ownership to Node 130 the following ocourrs:
Node 130 (the owner itself), 131 and 133 can access the volume. 132 cannot.
If I transfer the ownership to Node 132 the following ocourrs:
Node 132(the owner itself), 131 and 133 can access the volume. 130 cannot.
Also what we see:
If I open on Node 130 Hyper-V Manager I can connect to 131 and 133 but not to 132. I will get an RPC error
If I open on Node 132 Hyper-V Manager I can connect to 131 and 133 but not to 130. I will get an RPC error
We already have checked/done the following:
Disabled TCP Chimney

The above KB article is exactly what we are seeing but the recommended actions are already in place.
Do you have any further Idea what we can try to get the problem solved?
