Thanks Andrew! My first few attempts at playing around with the failure states are working as expected.
A few follow-ups below: --op-fail isn't the command you want though. > From the man page: > > -i, --op-inject=value > $rsc_$task_$interval@$node=$rc - Inject the specified > task before running the simulation > > -F, --op-fail=value > $rsc_$task_$interval@$node=$rc - Fail the specified task > while running the simulation > > Note the difference between the two descriptions: before vs. while. > --op-inject is the one you want. It is mostly useful for pretending a > recurring monitor failed and seeing what the cluster would do about > it. > > --op-fail on the other hand, is used for pretending that part of the > recovery process failed. > Your follow up description here is great, and makes more sense. I was reading "Fail the specified task" as literally, "here's my task, fail it and show me the results" I'd suggest to add a little paragraph in the man page to elaborate these points too. Also, can you tell me what all of the return codes are? Do I have to use integers, or do strings like "error" work? While we're on the subject of documentation / usability, I would also suggest to split out these two features into more parameters. (What would happen if I named my resource with an underscore?) Maybe something like: --op-pre-resource=[primitive name] --op-pre-task=[monitor|start|stop] --op-pre-interval=[integer] --op-pre-node=[hostname] --op-pre-rc=[error|timeout|other stuff] Then have similar --op-post-* parameters. Or whatever verbs make the most sense in the spirit of Pacemaker vocabulary. (pre/post, before/after, inject/fail, input/output, etc) And, examples are always awesome in man pages too. Of course, this is all great future version stuff, but that doesn't help all of the RedHat 6 people that will be using pacemaker 1.1 packages for the next ~10 years until RedHat 7 comes out. So I suppose documenting the old code in the online docs is a Good Thing. :-) Thanks again! --Cal
