Hello together,
i have here a setup with a 3 Member DAG Exchange 2010 SP2 UR4 on Win Srv2008 R2 fully patched.
Having the problem when i shutdown one of the three cluster nodes the cluster is getting offline and i get the following events:
event 4082 MSExchangeRepl event in the application log he replication network manager encountered an error while monitoring events. Error: Microsoft.Exchange.Cluster.Replay.AmClusterApiException: An Active Manager operation failed
event 1006 Cluster service was halted due to incomplete connectivity with other cluster nodes.
7024 Service Control Manager: The cluster service terminated with the service-specific error,
"The membership engine requested shutdown of the cluster service on this node."
7031 Service Control Manager: "The cluster service terminated unexpectedly. It has done this 1 time(s). Correction action: restart service.
i already installed some hotfixes and disabled tcp chimney. Hotfixes: 24708533, 2552040, 2550886, 2550886
and also did this :
cluster /prop SameSubnetDelay=2000:DWORD<o:p></o:p>
cluster /prop CrossSubnetDelay=4000:DWORD<o:p></o:p>
cluster /prop CrossSubnetThreshold=10:DWORD<o:p></o:p>
cluster /prop SameSubnetThreshold=10:DWORD<o:p></o:p>
i also rechecked network config. Looks good. cant find any connection issues. there are no firewalls between. having 2 networks, replika and mapi.
ping from one to another ok.
Clustermanager verify networks also ok, Test-replicationhealth also OK.
When i reboot one of thus 3 servers the whole cluster goes down..!!!
Please help.
thanks
best
martin
