Hi, For the last few days, I have been looking at the cman stack for our application. But I have a few questions. Our application is asymetric, we have a (duplicated active-passive) master server and work nodes. What I need from the cman is to know the state of each node and notification when the state changes. The policy decision (as to the fail-over, etc) would be taken by our master server. >From what I can see, cman/ucman can already do that. But, I need to monitor the application (have some kind of application heartbeat) so I can know if the app has deadlocked or segfaulted. And inform the masters (active/passive) of what happened so they can take the proper decision. It would also be nice to have a library version of fence, but for now I guess I can just system() fence_node (that does not use fenced, right?). Or something like stonithd (from the linux-ha folks) where the fencing equipement can be connected to different nodes, but be controlled in a transparent way. And, I want to retain control from my app... Oh yea, and I need something relatively stable before September too... Can I do that with your stuff? -- Olivier Crête ocrete@xxxxxxxxx Maximum Throughput Inc. -- Linux-cluster@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/linux-cluster
