crm resource trace <resource name> <operation> <resource name> - any defined primitive in the cluster <operation> - start, stop, monitor, probe
crm resource untrace <resource name><operation>
- If no <operation> is given, it will attempt to trace all operations for the provided resource.
- If tracing the monitor operation, number of trace files can grow quickly and should be monitored and cleaned up appropriately and periodically if tracing for extended periods.
- Adds the attribute "trace_ra=1" to the operation in the primitive definition.
Example: op monitor enabled="true" interval="20" timeout="45" trace_ra="1"
- crm resource tracing does not work for Stonith resources. Stonith resources scripts are located in the following directory "/usr/lib64/stonith/plugins/external/" and various methods can be used to debug these various types of scripts (bash, perl, python). For bash scripts you can modify the script and use "set -x" to enable logging of every command executed and will be logged to SYSLOG and "set +x" to disable logging.
- Resource tracing is only supported by OCF Resource Agents.
- Enabling resource trace will trigger resource restart. Pacemaker will stop and start the resource in order to activate tracing. Same apply to untrace command.
