Hello, I have written a custom resource agent for Informix servers in accordance to the OCF RA Developer's Guide http://www.linux-ha.org/doc/dev-guides/ra-dev-guide.html but I have some doubt if it properly integrates with RHCS's idiosyncrasies. I would have liked to save me the work finding out all the RedHat deviations, and would have taken a readily supplied agent for Informix Server resources if only I had found one. I found that I not only had to write the agent and simply place it in /usr/share/cluster (as far as I understand this would have sufficed in a Pacemaker cluster, albeit under a different directory path) I also had to tinker with /usr/share/system-config-cluster/misc/cluster.ng in order to have my extensions pass the XML validity check. Now my new <ifxdb/> tag is accepted in cluster.conf along with its paramtrezation via in the agent's meta-data dump as well as my definitions in cluster.ng, and I was able to successfully commit an ccs_tool update. These are the attributes and actions my agent supports so far: # /usr/share/cluster/ifxdb.sh meta-data|grep -E '(parameter|action) name' <parameter name="server" primary="1" unique="1"> <parameter name="home" required="1"> <parameter name="config" required="1"> <parameter name="version"> <parameter name="locale"> <parameter name="user"> <parameter name="dbdate"> <parameter name="dbmoney"> <parameter name="log"> <action name="start" timeout="60"/> <action name="stop" timeout="60"/> <action name="recover" timeout="180"/> <action name="status" depth="1" timeout="10" interval="15"/> <action name="monitor" depth="10" timeout="20" interval="30"/> <action name="meta-data" timeout="5"/> <action name="verify-all" timeout="5"/> rg_test shows its rules and I am able to start, stop and monitor (or status in RHCS mannerism) my Informix resources like e.g. # rg_test test /etc/cluster/cluster.conf start ifxdb ju_09tcp I can also enable, stop and relocate every service that contains an instance of my ifxdb resource via clusvcadm. As I made ample use of the ocf_log function (I prefer to have some meaningful output from the agents in the logs) at the command line when invoked through rg_test the agent verbosely reports what it's doing. What puzzles me is that I cannot see any of these logging entries when my agent is run by clurgmgrd. That it is run at all I can verify as on e.g. service startup the Informix server instance is successfully started. What puzzles me even more is that I cannot see any entries in /var/log/messages from the regular monitoring invocatins of the agent at given intervals according to above meta-data dump, so as if no resource monitoring checks are at all performed. And even worse, when I shutdown an Informix instance manually (e.g. omnode -ky) it doesn't get restarted by clurgmgrd even though *no* __independent_subtree attribute is defined in the ifxdb tags of cluster.conf. So although I can manually start, stop and relocate the affected services through clusvcadm, the whole rgmanager HA treatment seems dysfunctional to me. Is there anything or anywhere that I have forgotten to also manipulate to fully enable my custom resource agent?
