I ran into the same problem this summer. Unfortunately, the answer is that mostly, full documentation does not exist. However, there are a few scraps you may find very useful. First, here are some notes on the Open Cluster Framework's resource agent API: http://www.opencf.org/cgi-bin/viewcvs.cgi/specs/ra/resource-agent-api.txt?rev=HEAD If you're doing Red Hat Cluster Suite, there's more to it than the OCF-common parts. For example, RHCS metada is, I believe, specific to RHCS. I pointed out some holes in the documentation to Lon on IRC a few weeks ago, and he began writing this page: http://sources.redhat.com/cluster/wiki/RGManagerResourceAgents It's still very incomplete, but already very useful (thanks Lon!) Also, some things you can do for debugging: 1. Sprinkle some ocf_log calls in strategic places in your script: ocf_log info "some debugging statement, including a $OCF_variable" -> Make sure /usr/sbin is in your resource agent's path! 2. Configure logging so that your log statements make it to syslog. See http://sources.redhat.com/cluster/wiki/RGManager 3. Use rg_test, which I didn't know about at first. For example: sudo rg_test rules sudo rg_test test /etc/cluster/cluster.conf sudo rg_test test /etc/cluster/cluster.conf status service myservice sudo rg_test test /etc/cluster/cluster.conf start service myservice It turns out this is documented in the ResourceTrees page on the cluster wiki, but I didn't read that far on that page because I wasn't having any trouble understanding or configuring my resource trees. It's true that rg_test is useful for debugging resource trees, however it's also useful for troubleshooting resource agents. -- Cos -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
