[gpfsug-discuss] help with multi-cluster setup: Network is unreachable

[Jaime Pinto]

I only ask that we look beyond the trivial. The existing multi-cluster  
setup with mixed versions of servers already work fine with 4000+  
clients on 4.1. We still have 3 legacy servers on 3.5, we already have  
a server on 4.1 also serving fine. The brand new 4.1 server we added  
last week seems to be at odds for some reason, not that obvious.

Thanks
Jaime
