C.5. Debugging and Testing Services and Resource Ordering

You can debug and test services and resource ordering with the rg_test utility. rg_test is a command-line utility provided by the rgmanager package that is run from a shell or a terminal (it is not available in Conga). Table C.2, “rg_test Utility Summary” summarizes the actions and syntax for the rg_test utility.

Table C.2. `rg_test` Utility Summary

Action	Syntax
Display the resource rules that `rg_test` understands.	`rg_test rules`
Test a configuration (and /usr/share/cluster) for errors or redundant resource agents.	`rg_test test /etc/cluster/cluster.conf`
Display the start and stop ordering of a service.	Display start order: `rg_test noop /etc/cluster/cluster.conf start service servicename` Display stop order: `rg_test noop /etc/cluster/cluster.conf stop service servicename`
Explicitly start or stop a service.	Important Only do this on one node, and always disable the service in rgmanager first. Start a service: `rg_test test /etc/cluster/cluster.conf start service servicename` Stop a service: `rg_test test /etc/cluster/cluster.conf stop service servicename`
Calculate and display the resource tree delta between two cluster.conf files.	`rg_test delta cluster.conf file 1 cluster.conf file 2` For example: `rg_test delta /etc/cluster/cluster.conf.bak /etc/cluster/cluster.conf`
