[Pacemaker] virtual IP or real IP address
Hi I have a question. I've seen in the mailing list a lot of example with the IPAddr/IPAddr2 resource agent this resource agent manages the Virtual IP. Could anybody explain me why I have to create a virtual IP istead of using the real IP? for instance I have a cluster with 2 nodes and 1 tomcat on both machines My purpose is just to start and stop (maybe configure) these tomcat instances. I've created a configuration with the IPsrcaddr resource agent I think this should manage the real IP, isn't it? Could anybody point me in the right direction? thanks in advance gilberto ___ Pacemaker mailing list Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker

Could anybody explain me why I have to create a virtual IP istead of using the real IP? In brief, the idea is: - You have (say) two nodes in an HA cluster, each with its own unique IP address (i.e. the address you ssh to in order to administer that node). - The virtual IP address is a third, different IP, which is managed by the IPAddr2 RA. This is active on only one node at a time, and is managed by Pacemaker. - You set up colocation/ordering constraints so that the IPAddr2 resource runs on the same node as an instance of Apache (or whatever service you're providing). - Clients connect to that virtual IP, which can then failover to the other node, if the node it's running on dies.

Hi Michael Sorry, but was is machine63? You have custdevc03, 04 and 05. Did you mean: The machine that run resource res.ip.m63? --- YES my purpose is to have 3 apaches on 3 machines and I'd like to start/stop manually one of them. have I to assign a Vritual IP?
