=A0 =A0 =A0 =A0-i, --op-inject=3Dvalue<br>
=A0 =A0 =A0 =A0 =A0 =A0 =A0 $rsc_$task_$interval@$node=3D$rc - Inject the s=

=A0 =A0 =A0 =A0 =A0 =A0 =A0 $rsc_$task_$interval@$node=3D$rc - Fail the spe=
cified task<br>
while running the simulation<br>
<br>
Note the difference between the two descriptions: before vs. while.<br>
--op-inject is the one you want. =A0It is mostly useful for pretending a<br=
>
recurring monitor failed and seeing what the cluster would do about<br>
it.<br>
<br>
--op-fail on the other hand, is used for pretending that part of the<br>
recovery process failed.<br></blockquote><div><br>Your follow up descriptio=
n here is great, and makes more sense.=A0 I was reading &quot;Fail the spec=
ified task&quot; as literally, &quot;here&#39;s my task, fail it and show m=
e the results&quot;=A0 I&#39;d suggest to add a little paragraph in the man=
 page to elaborate these points too.=A0 Also, can you tell me what all of t=
he return codes are?=A0 Do I have to use integers, or do strings like &quot=
;error&quot; work?<br>

<br>While we&#39;re on the subject of documentation / usability, I would al=
so suggest to split out these two features into more parameters.=A0 (What w=
ould happen if I named my resource with an underscore?)=A0 Maybe something =
like:<br>

<br>--op-pre-resource=3D[primitive name]<br>--op-pre-task=3D[monitor|start|=
stop]<br>--op-pre-interval=3D[integer]<br>--op-pre-node=3D[hostname]<br>--o=
p-pre-rc=3D[error|timeout|other stuff]<br><br>Then have similar --op-post-*=
 parameters.=A0 Or whatever verbs make the most sense in the spirit of Pace=
maker vocabulary.=A0 (pre/post, before/after, inject/fail, input/output, et=
c)=A0 And, examples are always awesome in man pages too.<br>

<br>Of course, this is all great future version stuff, but that doesn&#39;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.=A0 So I suppose documentin=
g the old code in the online docs is a Good Thing.=A0 :-)<br>

<br>Thanks again!<br><br>--Cal<br><br></div></div><br>
