The primary one in fact :-) Its used extensively for the PE regression tests (look for pengine/regression.core.sh) and you can do things like take a config with no status section and then run: crm_simulate --in-place myconfig.xml --node-up mynode --simulate You can also do things like have parts of the resulting transition fail with --op-fail or simulate resource failures with --op-inject. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://developerbugs.linux-foundation.org/enter_bug.cgi?product=Pacemaker
