[Linux-cluster] Sounds like your cluster communication is happening over the T1, and not a local network.

Here's a very weird one. I have a cluster of web servers outgoing over a T1. 
When the T1 went down this morning, the cluster, which is all internal, non 
routable IP's, would not come back. All of the machines locked up around the 
loading DLM section on bootup.

Once the T1 came back, they all booted just fine and went into cluster mode.

What in the world would cause that? There aren't any external services 
required to fire up my local cluster, never were, it's always been fine 
before.
