Hello, Please excuse my direct mail, but I've received no conclusive answer on the linux-cluster mailing list, and I've seen your email on the Cluster Wiki home page. Please tell me what is the startup order for services in Red Hat Cluster 4.5 (rgmanager-1.9.68-1)? Are the services started in parallel, or are started one by one in the order as these appears in cluster.conf. I'm not talking about resources, or resource trees.
They are started in sequence as they appear in cluster.conf. I am not extremely familiar with EL4 but the behavior should be pretty much the same as other rgmanager releases. Fabio
