We have a Win2k3 SP1 two node cluster we use as a file server. Two weeks ago
we had to reboot a node following the reboot of our core network switches.
We have two resources that we balance between the two nodes of the cluster,
but after the reboot everything was on Node 1. Noting a performance lag we
attempted to move the resource to Node 2, however the IP resource failed
citing there was an IP Address conflict and gave us the MAC address, which
turned out to be the MAC address for Node 2.
We are able to move the Cluster resource (Cluster IP, Name, Quorum) to Node
2, but both of the File Server resources won't move and give us this same
problem.
Now all the times we tried moving resources Veritas Netbackup was backing up
the File Server resources. Could the running backups be preventing us from
bouncing a resource from Node 1 to Node 2, or could I have another issue?
Keep in mind this cluster is about 2 years old and this is the first time
we've had this issue.
Here is one of the errors:
