Hi all, I have two servers Dev01, and Dev02 (both with subnet mask of 225.225._225_.0) setup in a cluster. This works just fine. I tried to add a new server (Dev03) into the cluster but the log file states that " waited for 30s and no initial state was set by the discovery" and then makes this server the new master. This machine is in a subnet with a mask of 225.225._224_.0. This is the only difference between the three mmachines. Can this be a reason why this server cannot connect to Dev01 and Dev02 ?? If yes, is there a way wherein i can make this happen ? For all my servers the yml file contains the following props: 1. cluster.name: DevCluster 2. node.name: (Individual names of the machines for easy understanding) 3. discovery.zen.ping.timeout: 60s I have tried setting the discovery.zen.ping.unicast.hosts: ["IP addresses of Dev01 and Dev02"] on Dev03 but this doesnt help either. Could anyone point me in the right direction ? Thanking in advance. regards, -Parag ---
